Swift sonic thrombolysisreduces risk of bleeding
A new endovascular sonic lysis system reduces the risk of hemorrhage by dissolving clots faster than conventional catheter thrombolysis or mechanically assisted thrombectomy devices.
A new endovascular sonic lysis system reduces the risk of hemorrhage by dissolving clots faster than conventional catheter thrombolysis or mechanically assisted thrombectomy devices.
Dr. Constantino Peña, an interventional radiologist at the Baptist Cardiac & Vascular Institute in Miami, showed how the procedure works during a live televised case demonstration at the 2009 International Symposium on Endovascular Therapy. A 74- year-old patient with a blocked leg artery underwent ultrasound-enhanced thrombolysis with a tenecteplase/heparin infusion.The procedure required only half the usual thrombolytic dose and ended with a dissolved clot 12 hours later. Other techniques need at least 24 hours to be effective, which heightens bleeding risks associated with thrombolytics. BCVI specialists have performed the procedure on more than 100 patients using this technique, Peña said.
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.
