Alliance Pharmaceutical will kick off its marketing campaign for ultrasound contrast agent Imagent June 9 at the annual meeting of the American Society of Echocardiography in Orlando. The commercial release follows recent FDA approval of the agent to opacify the left ventricle in patients with suboptimal echocardiograms. Imagent, formerly known as Imavist, will be marketed by Alliance in partnership with Cardinal Health and inChord Communications. Imagent is manufactured from synthetic materials and packaged as a dry powder in a ready-to-use kit stored at room temperature. The powder is reconstituted with water to form an osmotically stabilized suspension of microscopic spheres, or microspheres, containing a perfluorochemical (perflexane) vapor and physiologic gases. Imagent is then injected intravenously into a patient undergoing a cardiac ultrasound exam.
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.
