Turbo inversion recovery magnitude (TIRM) images of muscle magnetic resonance images. (A–E) TIRM hyperintense signals in posterior paraspinal group of muscles, gluteal muscles as well as muscles of pelvis (obturator internus and externus), thigh adductors, trapezius, and supraspinatus muscles of the shoulder girdle. Axial images at calf levels (F) show TIRM hyperintense signals in gastrocnemius and soleus of bilateral calf. Fused TIRM whole body image (G) shows signal abnormalities involving multiple muscle groups of the shoulder, back, hip, pelvis, and thigh.
