Abstract
Objective: To describe the characteristic figures of femoral head avascular necrosis in MRI. Subject and method: 32 patients (39 femoral head) with avascular necrosis treated at 103 Military Hospital from March 2017 to August 2018. Calculate portion, compare serverity of each leg by Fisher exact test. Result: Double band sign 92.3%, crescent sign 30.8%, bone marrow oedema 71.8%. Necrosis A 28.3%, B 15.2%, C 23.9%, D 32.6%. Stage II 41%, III 43.6%, IV 15.4%. Conclusion: MR image show more detail characteristics figures of femoral head avascular necrosis.
