1. Hybrid Cardiac Ga-FAPI-4 PET/MRI in Dilated Cardiomyopathy: A Feasibility and Pilot Study Source: Radiology (RSNA) | June 16, 2026
This pilot study demonstrates the feasibility of combining Ga-68-labeled fibroblast activation protein inhibitor-4 (FAPI-4) PET with cardiac MRI for simultaneous molecular and structural imaging in patients with nonischemic dilated cardiomyopathy. The hybrid approach successfully detected fibroblast activation β a marker of active fibrosis β while MRI provided high-resolution structural detail in the same session. Results suggest this technique could offer a powerful new window into the pathophysiology of nonischemic cardiomyopathy beyond what either modality alone provides. URL: https://doi.org/10.1148/
2. Imaging Near Spinal Fixation Hardware at 0.55 T Compared With 3 T Source: JMRI / Wiley Online Library | June 2026
