GE Medical Systems, Epix Medical, and Mallinckrodt have begun a collaboration to advance the development of contrast agents for MR imaging of the heart. The companies hope to expand the use of MRI for diagnosing coronary artery disease, and will also focus on using MRI to diagnose peripheral vascular disease.
The use of MRI in the heart has been limited by the organ's rapid movement, which produces motion artifacts on MRI images. Under the nonexclusive partnership, GE, Epix, and Mallinckrodt hope to reduce the effect of cardiac motion on MRI images, develop software for 3-D visualization of arteries and veins, and optimize MRI sequences for intravascular MRI agents.
Epix of Cambridge, MA, is developing MS-325, a contrast agent for MR angiography that has been licensed to St. Louis-based Mallinckrodt. Research on the project will be conducted at Epix's headquarters, as well as at GE's corporate research facility in Schenectady, NY; GEMS headquarters in Milwaukee; the National Institutes of Health; and several academic centers.
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.
