This study capitalizes on the emerging technology of 19F MRI, using conventional 'thermally' polarized perfluorinated gas (perfluoropropane, or PFP) mixed with oxygen and studied with magnetic resonance imaging (MRI) to visualize ventilation. This technique has not been studied in children.
Children and adolescents (6-17 years old) with cystic fibrosis (CF) who have normal spirometry will undergo 19F MRI with the inhalation of an inert contrast gas to study ventilation. Comparisons will be made to a cohort of healthy children (6-17 years old) who will perform the same measures. The primary outcome measure is the feasibility of conducting these studies in the pediatric population. Parallel performance of multiple breath nitrogen washout (MBW) and spirometry will be used to compare the sensitivity of these outcomes to the presence of mild lung disease in these children. Finally, the investigators will compare data obtained during standard breath holds with a novel "free-breathing" technique that will eliminate the need for breath holds during MRI acquisition.

Contrast-Enhanced Ultrasound Biomarker for Prognostication and Guidance of Surgical Treatment in Acute Traumatic Spinal Cord Injury

Patients with traumatic spinal cord injury (tSCI) often suffer from spinal cord swelling inside the thecal sac, which contains the spinal cord and surrounding fluid, leading to increased pressure on the spinal cord tissue and decreased spinal cord blood flow at the site of injury. The combination of increased pressure and decreased blood flow causes vascular hypoperfusion of the spinal cord and exacerbates the severity of injury. This is also referred to as secondary injury. Thus, knowledge of spinal cord hypoperfusion would allow the treating physician to optimize the hemodynamic condition of the patient with acute spinal cord injury and potentially improve functional outcomes.

Investigation Into the Subharmonic Response of Three Contrast Agents in Static and Dynamic Flow Environments Using a Commercially Available Diagnostic Ultrasound Scanner

Article

Author: Forsberg, Flemming ; Wallace, Kirk ; Eisenbrey, John R. ; Eisenbrey, John R ; Vu, Trang ; Mayer, Hailee ; Machado, Priscilla ; Kim, Ga Won

OBJECTIVE:

The objective of this study was to investigate the subharmonic response of Lumason (also known as SonoVue; Bracco, Milan, Italy) to static and dynamic ambient pressures, with a direct comparison to Sonazoid (GE HealthCare, Oslo, Norway) and Definity (Lantheus Medical Imaging, MA, USA). The subharmonic responses of contrast agents can be exploited to perform subharmonic-aided pressure estimation.

METHODS:

The subharmonic response of each ultrasound contrast agent was evaluated in both a static and dynamic tank using a commercially available Logiq E10 clinical ultrasound scanner (GE HealthCare) equipped with subharmonic imaging (SHI) and an acoustic power-optimization algorithm. A C1-6 curvilinear array that transmits at 2.5 MHz and receives at 1.25 MHz in SHI mode was used to acquire the subharmonic signals. Data was transferred offline into MATLAB (MathWorks) to perform linear regression analysis and statistical testing for significance of the slopes (i.e., agent sensitivity).

RESULTS:

Sonazoid and Definity showed an inverse linear dependency between subharmonic signal and hydrostatic pressure at all pressure ranges (static and dynamic) tested, with maximum sensitivity under 50 mmHg in the static tank (-0.190 and -0.194 dB/mmHg for Sonazoid and Definity, respectively). Lumason exhibited a tri-phasic subharmonic behavior, beginning with a linear trend from 0 to 90 mmHg (sensitivity = 0.069 dB/mmHg), followed by a plateau from 100 to 130 mmHg, and an inverse linear trend from 140 to 200 mmHg (sensitivity = -0.137 dB/mmHg).

CONCLUSION:

The subharmonic response of Lumason is tri-phasic and differs from Sonazoid and Definity. Further investigation is needed to solidify understanding of the subharmonic behavior of Lumason to identify its usefulness for subharmonic-aided pressure estimation.

Ultrasound Biomarkers: Contrast-enhanced Ultrasound and Nakagami Imaging to Differentiate Benign and Malignant Choroidal Tumor

Article

Author: Raval, Vishal ; Oza, Sakshi ; Patil, Jagruti ; Kannan, Kiruthika ; Mercado-Shekhar, Karla P. ; Karmakar, Jayashree

PURPOSE:

We hypothesized that contrast-enhanced ultrasound (CEUS) using a microbubble technique to quantify microvascular changes and Nakagami imaging for tissue characterization would provide a new approach for diagnosing and differentiating benign and malignant choroidal lesions.

METHODS:

Five patients with choroidal melanoma (CM) and five patients with choroidal hemangioma (CH) were selected. Definity®, which contains perflutren microbubbles, was administered as a slow IV bolus (1 ml). CEUS was performed for 1 min postinjection of the contrast agent with ultrasound radiofrequency data acquired from 10 s to 60 s. The contrast value was calculated for the whole tumor region. A gradient magnitude method was used for each postcontrast frames with 1-second interval, and the time-averaged value in pixel intensity gradient of postinjection frames was estimated and reported. Based on the Nakagami statistical distribution model, two Nakagami parameters, m and Ω, where m (shape parameter), representing tissue heterogeneity, and Ω (scale parameter), representing the average energy of backscattered signals, were studied.

RESULTS:

CEUS analysis showed that the time-averaged estimated contrast was significantly higher (p = 0.008) for CH compared to CM. Furthermore, the time-averaged contrast within the normal choroidal region was significantly higher than the choroidal tumor region for both CH and CM (p = 0.001 for CH cases and p < 0.0001 for CM cases). Nakagami analysis showed that the m estimates were significantly higher (p = 0.032) for CH (m = 0.61) than for CM (m = 0.28), indicating that CH is a more heterogeneous tumor than CM. The Ω estimates were significantly higher (p = 0.0019) for CH (Ω = 0.15) compared to CM (Ω = 0.03). These results may be due to the more vascular structures in CH compared to CM.

CONCLUSIONS:

Quantitative intensity-based perfusion analysis using CEUS and backscattering tissue analysis using Nakagami imaging can provide valuable insights to differentiate benign and malignant choroidal lesions.

A Comparative Study of Commercially Available Ultrasound Contrast Agents for Sub-harmonic-Aided Pressure Estimation (SHAPE) in a Bladder Phantom

Article

Author: Schultz, William W ; Sack, Bryan S ; Daignault-Newton, Stephanie ; Kalayeh, Kourosh ; Chen, Amy ; Yeras, Sophia ; Fowlkes, J Brian

OBJECTIVE:

The goal of this study was to evaluate the performance of different commercial ultrasound contrast microbubbles (MBs) when measuring bladder phantom pressure with sub-harmonic-aided pressure estimation (SHAPE) methodology. We hypothesized that SHAPE performance is dependent on MB formulation. This study aimed to advance the SHAPE application for bladder pressure measurements in humans.

METHODS:

Using a previously designed and built bladder phantom, we tested four different commercial agents: Definity, Lumason, Sonazoid and Optison. A standard clinical cystometrogram (CMG) system was used to infuse a MB-saline mixture into the bladder phantom to measure pressure. Ultrasound imaging was performed using the GE Healthcare LOGIQ E10 scanner.

RESULTS:

All agents showed a predicted inverse linear relationship between change in pressure and SHAPE signal. However, they differ from each other in terms of stability, linear correlation, sensitivity to pressure and error. Generally, Definity and Lumason showed the highest performance during the SHAPE-based bladder phantom pressure assessments.

CONCLUSION:

Our results show that the SHAPE signal decreases as bladder phantom pressures increases, regardless of the agent or CMG phase, suggesting the possibility of using SHAPE for measuring bladder pressure without a catheter. However, the efficacy of SHAPE in measuring pressure varies by MB formulation. These observations support using Lumason and Definity in a human subject feasibility study as we advance toward a catheter-free solution for measuring voiding bladder pressure via SHAPE.

Porous crystals bind fluorine-containing greenhouse gases

Fluorine-containing gases -- including so-called per- or polyfluorinated hydrocarbons, or PFCs -- have a significant share in global warming. Researchers recently developed new crystalline materials that can selectively adsorb the molecules of such carbon-fluorine bonds. They hope that these porous crystals may be useful for targeted binding and recovery of PFCs. Emissions of greenhouse gases contribute significantly to global warming. Not only carbon dioxide (CO2) but also fluorine-containing gases -- including so-called per- or polyfluorinated hydrocarbons, or PFCs -- have a significant share in this development. Researchers at the Institute of Organic Chemistry of Heidelberg University led by Prof. Dr Michael Mastalerz recently developed new crystalline materials that can selectively adsorb the molecules of such carbon-fluorine bonds. The Heidelberg researchers hope that these porous crystals may be useful for targeted binding and recovery of PFCs. Polyfluorinated carbons are organic compounds of various lengths in which the hydrogen atoms of alkanes are partly or fully replaced by fluorine atoms. These atoms are chemically highly stable. They are not ubiquitous in nature and are used mainly for etching processes in the semiconductor industry, in eye surgery, and in medical diagnostics as contrast enhancers for certain ultrasound examinations. "Unlike CO2, which is integrated in natural material cycles, PFCs accumulate in the atmosphere and stay there for several thousands of years before breaking down," stresses Prof. Mastalerz. Compared to carbon dioxide, PFCs thus have a much greater global warming potential -- the impact of one PFC molecule is virtually equal to 5,000 to 10,000 CO2 molecules. According to the researcher, that makes polyfluorinated hydrocarbons a permanent problem that is not only contributing to global warming now but accelerating it as well. With his research group at the Institute of Organic Chemistry of Heidelberg University, Prof. Mastalerz has developed a new type of crystalline material that can adsorb polyfluorinated hydrocarbons highly selectively, i.e., binding them to its interior surface. The porous crystals are based on shape-persistent organic cage compounds that carry fluorine-containing side chains on the interconnected struts. These side chains react according to the "like attracts like" principle via fluorine-fluorine interactions with the PFC molecules, ensuring they are deposited on the inner surface of the material. In their experiments, the Heidelberg researchers proved that the crystals they developed bind certain fluorine-containing gases such as octafluoropropane or octafluorocyclobutane approximately 1,500 to 4,000 times more strongly than dinitrogen, the main component of air. According to Prof. Mastalerz, these numbers represent extraordinarily high selectivities to bind such PFCs. Currently Prof. Mastalerz and his team are working on further increasing the selectivity of the crystals and transferring the process to other fluorinated gases, such as those used in medical anaesthesia. "I see enormous potential for development in this area," emphasises the researcher. He hopes that the adsorbent can be used for recovery of polyfluorinated hydrocarbons at their point of use. The German Research Foundation funded the research.

Lantheus Receives U.S. FDA Approval of PYLARIFY® (piflufolastat F 18) Injection, the First and Only Commercially Available PSMA PET Imaging Agent for Prostate Cancer

PYLARIFY will be available immediately to imaging centers in parts of the mid-Atlantic and southern regions and is expected to be broadly available throughout the U.S. by year end NORTH BILLERICA, Mass.--(BUSINESS WIRE)-- Lantheus Holdings (the “Company”) (NASDAQ: LNTH), an established leader and fully integrated provider of innovative imaging diagnostics, targeted therapeutics and artificial intelligence solutions to find, fight and follow serious medical conditions, announced today that the U.S. Food and Drug Administration (FDA) has approved PYLARIFY, an F 18-labeled prostate-specific membrane antigen (PSMA) targeted positron emission tomography (PET) imaging agent to identify suspected metastasis or recurrence of prostate cancer. PYLARIFY is the first and only commercially available approved PSMA PET imaging agent for prostate cancer. The product will be immediately available in parts of the mid-Atlantic and southern regions and availability is expected to rapidly expand over the next six months with broad availability across the U.S. anticipated by year end. “The FDA approval of PYLARIFY is a significant milestone for Lantheus and the prostate cancer community in the United States. We believe PYLARIFY represents a paradigm shift in the identification and management of patients with suspected metastasis or recurrent prostate cancer, providing more accurate and earlier detection of disease than conventional imaging so that doctors, along with patients and their families, can make more informed treatment decisions,” said Mary Anne Heino, President and Chief Executive Officer of Lantheus. “I would like to thank the patients who participated in our clinical trials, the study investigators and our employees, whose efforts made this achievement possible.” Identification of suspected metastatic disease in men considering initial definitive therapy is important to optimize treatment planning and to avoid futile interventions. Of men with localized prostate cancer who undergo initial curative intent/management, up to 50% may experience recurrence of their disease within ten years of treatment.1 Recurrent disease is often detected by a rise in serum prostate-specific antigen (PSA) levels; however, conventional imaging, especially at low PSA levels, is not able to identify the location and extent of the disease in the majority of cases.2,3 PYLARIFY was developed to target PSMA, a protein that is overexpressed on the surface of more than 90% of primary and metastatic prostate cancer cells.4 PYLARIFY binds to the target, enabling the reader of the PET scan to detect and locate the disease. Cyclotron production of F 18 offers high batch capacity and high image resolution, and F 18’s 110-minute half-life allows for wide geographic distribution.5,6 “Conventional imaging has significant limitations in detecting prostate cancer, both in initial staging and when the cancer has recurred or spread after initial primary treatment. Specifically, standard imaging poorly detects the early spread to distant organs, such as the lymph nodes, bones, and other organs,” said Michael J. Morris, M.D., Prostate Cancer Section Head, Genitourinary Medical Oncology, Memorial Sloan Kettering Cancer Center and the Lead Study Investigator in the CONDOR trial and Study Investigator in the OSPREY trial. “PYLARIFY can detect the spread of disease well before standard imaging and can be a transformative diagnostic tool that helps clinicians develop treatment plans based on a much more accurate understanding of a patient’s distribution of disease.” “We believe today’s approval is a game-changer for men facing prostate cancer," said Jamie Bearse, Chief Executive Officer of ZERO - The End of Prostate Cancer, a Patient Advocacy Group. "Having a diagnostic tool that allows doctors to see suspected metastatic or recurrent prostate cancer earlier, anywhere in the body, is a significant step forward and will have a tremendous impact on patients' lives.” The approval of PYLARIFY is based on data from two Company-sponsored pivotal studies (OSPREY and CONDOR) designed to establish the safety and diagnostic performance of PYLARIFY across the prostate cancer disease continuum. Results from OSPREY (Cohort A) demonstrated improvement in specificity and positive predictive value (PPV) of PYLARIFY PET imaging over conventional imaging in men at risk for metastatic prostate cancer prior to initial therapy. CONDOR studied men with biochemical recurrent prostate cancer. In patients with biochemical recurrent prostate cancer and non-informative baseline imaging, PYLARIFY demonstrated high correct localization and detection rates, including in patients with low PSA values (median PSA 0.8 ng/mL). In the clinical trials, PYLARIFY was well tolerated. In OSPREY and CONDOR, 593 patients with various states of prostate cancer were exposed to a single dose of PYLARIFY. Adverse reactions (headache, dysgeusia and fatigue) were reported in ≤ 2% of patients within the studies. In addition, a delayed hypersensitivity reaction was reported in one patient (0.2%) with a history of allergic reaction. About PYLARIFY® PYLARIFY® (piflufolastat F 18) injection (also known as 18F-DCFPyL or PyL) is a fluorinated small molecule PSMA-targeted PET imaging agent that enables visualization of lymph nodes, bone and soft tissue metastases to determine the presence or absence of recurrent and/or metastatic prostate cancer. For men with prostate cancer, PYLARIFY PET combines the accuracy of PET imaging2, the precision of PSMA targeting and the clarity of an F 18 radioisotope5 for superior diagnostic performance. The recommended PYLARIFY dose is 333 MBq (9 mCi) with an acceptable range of 296 MBq to 370 MBq (8 mCi to 10 mCi), administered as a bolus intravenous injection.1,5,7,8,9 About Prostate Cancer Prostate cancer is the second most common form of cancer affecting men in the United States -- an estimated one in eight men will be diagnosed with prostate cancer in their lifetimes. The American Cancer Society estimates that in 2021, almost 250,000 new cases of prostate cancer will be diagnosed, and more than 30,000 men will die of the disease. Approximately 3.1 million men in the United States currently count themselves as prostate cancer survivors.10 PYLARIFY® (piflufolastat F 18) Injection Indication PYLARIFY® (piflufolastat F 18) Injection is a radioactive diagnostic agent indicated for positron emission tomography (PET) of prostate-specific membrane antigen (PSMA) positive lesions in men with prostate cancer: with suspected metastasis who are candidates for initial definitive therapy. with suspected recurrence based on elevated serum prostate-specific antigen (PSA) level. Important Safety Information Contraindications None. Warnings and Precautions Risk of Image Misinterpretation Imaging interpretation errors can occur with PYLARIFY imaging. A negative image does not rule out the presence of prostate cancer and a positive image does not confirm the presence of prostate cancer. The performance of PYLARIFY for imaging of patients with biochemical evidence of recurrence of prostate cancer seems to be affected by serum PSA levels. The performance of PYLARIFY for imaging of metastatic pelvic lymph nodes prior to initial definitive therapy seems to be affected by risk factors such as Gleason score and tumor stage. PYLARIFY uptake is not specific for prostate cancer and may occur with other types of cancer as well as non-malignant processes and in normal tissues. Clinical correlation, which may include histopathological evaluation of the suspected prostate cancer site, is recommended. Hypersensitivity Reactions Monitor patients for hypersensitivity reactions, particularly patients with a history of allergy to other drugs and foods. Reactions may be delayed. Always have trained staff and resuscitation equipment available. Radiation Risks Diagnostic radiopharmaceuticals, including PYLARIFY, expose patients to radiation. Radiation exposure is associated with a dose-dependent increased risk of cancer. Ensure safe handling and preparation procedures to protect patients and health care workers from unintentional radiation exposure. Advise patients to hydrate before and after administration and to void frequently after administration. Adverse Reactions The most frequently reported adverse reactions were headaches, dysgeusia and fatigue, occurring at rate of ≤2% during clinical studies with PYLARIFY. In addition, a delayed hypersensitivity reaction was reported in one patient (0.2%) with a history of allergic reactions. Drug interactions Androgen deprivation therapy (ADT) and other therapies targeting the androgen pathway, such as androgen receptor antagonists, may result in changes in uptake of PYLARIFY in prostate cancer. The effect of these therapies on performance of PYLARIFY PET has not been established. To report suspected adverse reactions for PYLARIFY, call 1-800-362-2668 or contact FDA at 1-800-FDA-1088 or .
