Title: X-ray and CT Diagnosis of Avascular Necrosis of Femoral Head
Abstract: Objective To evaluate the value of X-ray and CT imaging in the diagnosis of avascular necrosis of femoral head.Methods X-ray and CT findings of the femoral head were studied in 67 patients retrospectively which were compared with ability to demonstrate the early ANFH.Results 26 patiets with Ⅰ~Ⅱ ANFH were detected by X-ray imaging, the diagnostic accuracy rate was 38.8 %.While 46 patiets with Ⅰ~Ⅱ ANFH were detected by CT imaging, the diagnostic accuracy rate was 68.6 %.Conclusion It is difficult to detect the early avascular necrosis of femoral head. CT technique is an effective and reliable method in diagnosing early avascular necrosis of femoral head, and superior to X-ray examination.
