The application of MRI in gluteal muscle contracture / 中华放射学杂志

ABSTRACT

Objective To evaluate the MRI findings and its diagnostic value in gluteal muscle contracture (GMC). Methods Eleven clinic or operation confirmed GMC patients were examined by plain X-ray and MRI. Conventional T 1WI and T 2WI MR imaging were performed and FFE-T 2WI (fast field echo-T 2WI) was also scanned. CT scan was conducted in 5 cases. Results 11 GMC patients were all diagnosed by MRI. Conventional T 1WI and T 2WI could only show the atrophy of gluteal muscles, while FFE-T 2WI could directly show the fibrous band of gluteal muscle and its fascia, and the fibrous band appeared as low signal intensity on FFE-T 2WI sequence. Conclusions MRI is the efficient modality in imaging the fibrous band for GMC patients, and FFE-T 2WI is the most valuable sequence. MRI is very helpful in the diagnosis and treatment of GMC.
