Interventional rads can offer ablation for varicose veins
Interventional radiologists can use ultrasound guidance and radio-frequency ablation to treat varicose veins, researchers at the Society of Cardiovascular and Interventional Radiology annual meeting said.
Interventional radiologists can use ultrasound guidance and radio-frequency ablation to treat varicose veins, researchers at the Society of Cardiovascular and Interventional Radiology annual meeting said.
Performed under local anesthetic, a catheter is guided via ultrasound to the saphenous vein to allow RF ablation to heat the inner wall of the vein and shrink it, closing off the leaky valves. Nearby veins take over circulation of blood in the legs. The technique received FDA approval last year and is already being offered at 25 centers throughout the U.S. (Search for marzano.)
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.
