Periannular uptake. (IMAGE)
Caption
Figure 3. Periannular uptake. Representative examples show hybrid, fused PET/MRI in patients with findings suggestive of periannular uptake. (A) Axial view with uptake in basal lateral and basal septal regions, surrounding mitral annulus. (B) T2 values are globally increased, especially in basal septum. (C) Axial view with increased 18F-FDG uptake in regions surrounding mitral annulus. (D) T1 values are increased in basal septum. (E) Sagittal view with increased uptake in basal segments surrounding mitral valve annulus. (F) ECV values are increased, especially in basal to mid-septum. SUV scale is 0–5 g/mL. AHA = American Heart Association; ECV = extracellular volume.
