New research presented this month at the American Society of Echocardiography meeting in Washington, DC, indicates that the use of microbubble contrast agents with ultrasound scans of the heart can work to break up blood clots that cause strokes and heart attacks. In a study presented June 14 at the ASEs 10th annual scientific sessions, University of Nebraska Medical Center researchers compared the efficacy of ultrasound scans alone to ultrasound scans with an injection of perfluorocarbon microbubbles. Dr. Thomas Porter and colleagues discovered that adding the contrast to cardiac ultrasound therapy scans helped to dissolve blood clots.
Porter and his team did their research by producing a laboratory simulation of blood vessels with clots using tubing, saline, and clots gathered from pigs. Porter explained that the combination of ultrasound waves and microbubbles increased motion around the clots, causing them to fragment. The study points to another nonsurgical method of dispelling clots that lead to stroke or heart attack.

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.
