Sonus discusses new agent at AHA show

Researchers working with ultrasound contrast developer Sonus Pharmaceuticalspresented data about a new contrast agent, QW7437, at last week'sAmerican Heart Association meeting in New Orleans. The Bothell,WA, company said QW7437 is a third-generation agent that studiesindicate may be capable of producing myocardial perfusion at lowdoses with no hemodynamic effects.
Researchers from the University of California at San Diegoworking with the new agent presented data from animal studiesfor the first time at a major medical conference. QW7437 is aphase-shift emulsion that is stabilized with a negative-chargedsurfactant.
Investigators at the AHA meeting also presented data on thecompany's lead EchoGen agent, including an animal study by DukeUniversity researchers in which EchoGen was used to make 3-D measurementsof the left ventricle muscle mass in a single cardiac cycle.
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
