ISMRM: AI spots ischemic heart disease on low GBCA dose images
An AI-based framework was highly accurate for detecting myocardial ischemia, even on images acquired with 90% less gadolinium.

Representative stress perfusion CMR case with 80% contrast dose reduction. Pixel-wise MBF maps and AHA 16-segment bull's eye plots are shown for full-dose and reduced-dose acquisitions. When analyzed using the proposed MST deep learning method, the reduced-dose data closely matches the full-dose data across basal, mid, and apical slices. In contrast, Fermi-deconvolution shows good agreement in apical and mid slices but overestimates MBF in some basal segments, indicating reduced accuracy under low-dose conditions.

PET/CT metric improves outcome predictions in Pluvicto patients

The inclusion of total tumor volume (TTV) produces prediction models with better discriminatory ability.
March 31, 2026
PSMA-PET images. (A) Representative examples illustrate the variability in the total tumor volume (TTV) among patients stratified by the number of metastatic lesions. (B) Case examples demonstrate TTV segmentation across a range of TTV values. Notably, as the tumor volume increased, a visible decrease in radiopharmaceutical uptake by normal organs is observed, particularly in the salivary glands, kidneys, and liver (denoted by brackets), a phenomenon known as the “sink effect.” SUV = standardized uptake value.
