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.

SNMMI: PET/MRI helps manage patients with chronic spinal pain
By Will Morton
F-18 FDG-PET/MRI scans can detect previously unidentified locations of chronic spinal pain.
June 23, 2025
Coronal fused FDG-PET/MRI image of a patient with right upper back pain demonstrates asymetric uptake in the right trapezius muscle without abnormality on MRI to suggest edema or denervation injury. Trigger point lidocaine injection of the area based on PET/MRI findings resulted in complete relief of symptoms (pain score reduced to 0 from a baseline of 6).
