A large metastudy indicates that endovascular repair is better and safer than surgery for the treatment of blunt thoracic aortic trauma.
Dr. Eric K. Hoffer and colleagues at Dartmouth Medical School's vascular and interventional radiology unit reviewed 19 published studies comparing 262 endograft repairs versus 376 open surgeries. They found that the 30% death rate associated with EVAR for thoracic aorta injury was half the rate associated with open surgery and intensive care methods. Stenting further reduced mortality by almost 10% in some cases, likely as a result of decreased systemic stress afforded by endovascular repair. EVAR also brought down the risk of paraplegia, a frequent surgical complication. Results were published in the August issue of the Journal of Vascular and Interventional Radiology.
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.
