[Abstract] Objective: To evaluate the diagnostic value of muscle hematoma in lower limb using the diffusion-weighted imaging (DWI) and susceptibility-weighted imaging (SWI).Materials and Methods: Retrospective analysis between June 2009 to June 2011 by surgery or biopsy and clinical follow-up confirmed the muscle hematoma MRI data of 15 case, all patients were performed with MRI conventional sequences, including T1WI, T2WI, DWI and SWI.Results: In MRI conventional sequences acute and subacute hematoma showed early was to go with muscle or muscle gap consistent long spindle-shaped, in T1WI as equal/high signal intensity, in T2WI showed equal or higher signa intensity. In DWI lesions showed low signal center, surrounded by high signal and SWI showed high signal-based, central was not irregular flakes low signal, visible in varying degrees around the ring of low signal. Late subacute or chronic hematoma was irregular round or fusiform, T1WI and T2WI showed high signal on the upper and lower showed low signal, and the formation of clear liquid fluid level, DWI and high signal SWI upper and lower showed low signal.Conclusions: DWI and SWI sequence can be compared with conventional MR sequences provide more information, as an important complement conventional sequence, can significantly reduce acute and subacute hematoma early misdiagnosis and missed diagnosis.
