MR Imaging of Traumatic Marrow Edema with STIR Sequence / 实用放射学杂志

ABSTRACT

Objective To assess the clinical application of STIR sequences in the diagnosis of traumanic marrow edema. Methods Twenty-eight cases of traumanic marrow edema were found on MRI exam. Except routine SE T1WI?FSE T2WI and GE T2*WI, STIR sequence was performed.Results Thirty-six bone marrow edema were found in 28 cases, 24 lesions(67%)were all hypointensity on T1WI,12 lesions(33%)were depicted on T2WI, 8 lesions presented hypointensity and 4 mild hyperintensity. 29 lesions(80%)on T2*WI,14 were hypointensity and 15 hyperintensity. With STIR, 36 lesions(100%) displayed as hyperintensity signal more clearly.Conclusion STIR is good delineating traumanic marrow edema.
