摘要
目的探讨CT在股骨头缺血坏死病人诊断中的应用。方法对 5 0例 ( 70髋 )股骨头缺血坏死 (ANFH)病人及 3 0例 ( 4 0髋 )正常人进行CT检查 ,并将其结果与MRI及X线平片分期进行对比分析。结果5 0例中Ⅰ期者X平片为 40例 ,CT为 2 5例 ;Ⅱ期者X平片为 15例 ,CT为 3 0例 ;余10例Ⅲ～Ⅳ期者X线平片与CT相同。结论虽然CT诊断不如MRI灵敏 ,但在显示股骨头骨折方面明显优于MRI及X线平片。因此 ,CT诊断可以提高疾病分期级别 。
Objective To explore the application of CT in the diagnosis for avascular necrosis of femoral head (ANFH).MethodsForty normal hips from thirty healthy individuals (served as control) and seventy hips from fifty patients with ANFH were examined by CT scanning.The CT findings were compared with those of radiograghy and MRI(magnetic resonance imaging).ResultsForty out of fifty ANFH patients belonged to the first stage damage in radiographic examination, but there were only twenty-five ANFH patients with the first stage damage when CT scanning was carried out;fifteen ANFH patients were identified by radiography as second stage damage, whereas thirty patients were identified within second stage by CT scanning. The same results were obtained by radiography and CT scanning in the identification of the third-fourth stage damage for the other ten patients.ConclusionsIn the diagnosis of ANFH,CT is less sensitive than MRI, but its display is much clearer than MRI and plain film on showing fracture of femoral heads. Therefore, the diagnostic stages could be regraded by CT,it might be helpful for the choice of therapeutic procedure. [
