Iso-osmolar agent showshigher renal failure rate
Radiologists hoped the introduction of isoosmolarcontrast media would eliminatesevere adverse reactions to x-ray contrast.Alas, it was not to be.
Radiologists hoped the introduction of isoosmolar contrast media would eliminate severe adverse reactions to x-ray contrast. Alas, it was not to be. A large retrospective Swedish study identified a significantly higher rate of renal failure among patients administered iso-osmolar iodixanol (Visipaque) compared with patients who received low-osmolar ioxaglate (Hexabrix).
Dr. Per Liss and colleagues at the University of Uppsala presented their evaluation of 23,224 patients at the 2008 RSNA meeting. They found that 1.7% of patients who received iodixanol developed primary or secondary renal failure within 12 months of administration. The 12-month renal failure rate for patients who received ioxaglate was 0.8%.
Study Reaffirms Low Risk for csPCa with Biopsy Omission After Negative Prostate MRI
December 19th 2024In a new study involving nearly 600 biopsy-naïve men, researchers found that only 4 percent of those with negative prostate MRI had clinically significant prostate cancer after three years of active monitoring.
Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
