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.

Examples of DAWM on FLAIR MRI slices. Transversal slices of 1.5T FLAIR MRI scans. For visualization only, brains were skull-stripped and DAWM is shown with dotted lines (occipital DAWM is red, parietal DAWM is orange). Top row images (25% of lobar WM) show larger, more confluent configurations of DAWM, extending beyond the slices shown here.

Transaxial Zr-89 NMK89 PET/CT images 1, 24, 72, and 168 hours after injection showing increasing uptake in pancreatic tail adenocarcinoma. Maximum standard uptake value (SUV) in the pancreatic mass is 14 at 168 hours post-injection (crosshairs). PET SUV scale used for windowing was 0 to 10.
