Transverse T2-weighted and TIRM sequence muscle magnetic resonance images. A slightly increased signal was detected in the posterior compartment of the thigh, in the semimembranosus and semitendinosus muscles (a: T2-weighted, b: TIRM). A highly increased signal intensity in TIRM sequences was detected at the level of the lower leg, indicating obvious muscular edema (d). A mild increase in the signal intensity was observed in the T2 sequence of soleus and tibialis anterior muscles, indicating fat replacement (c)
