[Abstract] Objective: To assess the value of short-tau inversion recovery (STIR) sequence in dermatomyositis (DM) and polymyositis (PM) and investigate its application in clinical practice.Materials and Methods: Twelve patients with a diagnosis of DM/PM were respectively evaluated using clinical examination and muscle biopsy-proved. All the patients were preformed with MRI of their thigh, including the images of T1-weighted imaging (T1WI); T2-weighted imaging (T2WI) and STIR sequences. The abilities of detecting lesions among these sequences were observed and compared.Results: All of included patients were detected abnormal MRI appearances of their thigh muscle, which representing myositis in 11 cases, fasciitis in 8 cases, subcutaneous inflammation in 9 cases, and myoatrophy with fatty infiltration in 1 cases. The STIR sequence discovered all of abnormal lesions; T1WI sequence found 5 cases of subcutaneous inflammation and 1 cases of myoatrophy, but none of myositis or myofasciitis were found; T2WI sequence found 6 cases of myositis, one case of myoatrophy and 2 cases of subcutaneous inflammation, none of myofascitis were found. On the STIR sequence, compared with other bilateral thigh muscle groups, 7 patients showed higher signal intensity on medial and rear thigh muscle groups, had confirmed by pathology that muscle edema were seriously than other groups.Conclusions: With high resolution and high sensitivity of soft tissue, the STIR sequence can significantly improve the detection rate of soft tissue inflammation. The signal intensity can subjectively reflected the degree of muscle damage, and it has important value in clinical practice.
