Contrast media reactions rarely happen, study finds
Concerns about the potential adverse reactions of patients to iodinated and gadolinium-based contrast agents used with CT and MRI may be more perceived than real, according to Mayo Clinic researchers.
Concerns about the potential adverse reactions of patients to iodinated and gadolinium-based contrast agents used with CT and MRI may be more perceived than real, according to Mayo Clinic researchers.
Dr. Christopher H. Hunt and colleagues in Rochester, MN, reviewed 456,930 episodes of contrast media administration. From this base, 522 cases of mostly mild adverse effects were identified. Reactions included nausea, vomiting, and skin rashes. Only 16 cases, 10 severe reactions to low-osmolar iodinated agents and six to gadolinium, needed transfer to an emergency department for further observation and treatment. One patient died, but possibly due to unrelated causes. Pretreatment with corticosteroids helped bring down the incidence of adverse effects (AJR 2009;193[4]:1124-1127). Adverse contrast reactions can occur, but they are rarely severe and most require only observation and supportive care, Hunt said.
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.
