Abstract：Objective: To assess the MR characteristics of lumbosacral superficial fasciitis. Methods: Eighty-nine cases of patients(53 males and 36 females) with clinical diagnosis of lumbosacral superficial fasciitis because of low back pain or(and) leg pain were included in this study. MR examination of low back was performed on a 3.0T or a 0.35T MR scanner for all the patients. The scanning sequences included spin echo T1WI(SE T1WI), fast spin echo T2WI(FSE T2WI), short time inversion recovery(STIR) or spectral attenuated inversion recovery(SPAIR). Result: Lesions of long T1 and long T2 signal intensity which were high signal intensity on STIR and SPAIR with clear border were seen in the lumbosacral superficial fascia of all the 89 cases. Conclusion: MRI has high sensitivity and specificity in diagnosis of lumbosacral superficial fasciitis and may help in avoiding misdiagnosis and missed diagnosis.
