| Abstract: | Objective To discuss the diagnostic value of MRI fat suppression sequence for acute bone contusion. Methods Retrospectively analyzed the MRI data of 120 bone contusion patients whose results of X-ray and CT examination, and summarized the detectable rate from each sequence. Results The sensibility of STIR sequence is better than SE sequence, and the detectable rate of STIR, T1WI, T2WI is 100%, 72.8% and 43.9%, respectively, which has statistical significant difference（P〈0.05）. Conclusion MRI has high sensibility to marrow changes. MRI fat suppression sequence can clearly show marrow edema, bleeding and trabecular microfracture which can not be showed by X-ray examination. |
