Adenosine rest-stress perfusion may represent nearly half the imaging volume at some clinics, but due to safety questions some physicians are sticking with dobutamine for pharmacological stress testing.
Adenosine rest-stress perfusion may represent nearly half the imaging volume at some clinics, but due to safety questions some physicians are sticking with dobutamine for pharmacological stress testing.
A study of adenosine safety conducted by researchers at St. Marien Hospital in Bonn, Germany, may put those concerns to rest. Dr. Karol Miszlaski-Jamka did record minor side effects, such as facial flushing and mild shortness of breath, in 81% of the 645 patients who underwent adenosine-stress contrast MR. But major side effects were limited, including 23 cases of transient high-degree atrioventricular block that resolved spontaneously, one case of severely increased blood pressure, and two instances of claustrophobia.

Can CT-Based AI Radiomics Enhance Prediction of Recurrence-Free Survival for Non-Metastatic ccRCC?
April 14th 2025In comparison to a model based on clinicopathological risk factors, a CT radiomics-based machine learning model offered greater than a 10 percent higher AUC for predicting five-year recurrence-free survival in patients with non-metastatic clear cell renal cell carcinoma (ccRCC).
