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.

Myocardial involvement. Representative examples show fused PET/MRI images in patients with findings suggestive of myocarditis. (A and B) Short-axis view of increased F-18 FDG uptake in basal septum segments (A), colocalized with area of increased T2 values (B) on parametric mapping. (C and D) Prominent F-18 FDG uptake in middle anterolateral and inferolateral walls (C), matching area of increased T1 values (D). (E and F) Short-axis views of avid F-18 FDG uptake in basal inferior and inferolateral walls (E), matching areas of increased extracellular volume (F). SUV scale is 0-5 g/mL.
