[MRI findings of muscular sarcoidosis].
MRI characteristics of number lesions were studied in eight patients with sarcoidosis proved by Ga scintigraphy. T2 weighted image in spin echo method and low flip angle method were employed. The localization of lesion detected by Ga scintigraphy was quite similar to that of lesions found by MRI, but lesions were more clearly detectable in MRI than Ga. MRI could identify anatomical localization of muscular lesions. Two characteristic MRI findings were observed; one was high intensity in the whole lesion, and another was high intensity in periphery with low intensity in central lesion. MRI is a useful tool for more accurate diagnosis of muscular lesions in sarcoidosis.
