CT、MRI在早期股骨头坏死诊断中的应用价值

摘要

Objective:To investigate the value of tomography magnetic ( CT) and magnetic resonance imaging ( MRI) in the diagnosis of early avascular necrosis of the femoral head .Methods:70 cases of early femoral head necrosis were divided into the observation group and the control group according to the different examination methods.Observation group of patients were examined with MRI, control group patients with CT.Re-sults:The detection rate and total detection rate of observation group in phase 1 and phase 2 were remarkably higher than those in control group ( P <0.05).In the observation group, the display rate of the trabecular structure of the trabecular bone was significantly higher than that of the con-trol group ( P <0.05).Conclusion:The detection rate of MRI in the early stage of femoral head necrosis was significantly better than that of CT. MRI can effectively display the typical signs of patients , and it can be used as the first choice for the early detection of femoral head necrosis .%目的：探讨电子计算机断层扫描（computer tomography，CT）、磁共振成像（magnetic resonance imaging，MRI）在早期股骨头坏死诊断中的应用价值。方法：将70例早期股骨头坏死患者按检查方法的不同分为观察组和对照组。观察组患者行MRI检查，对照组患者行CT检查。结果：观察组1期、2期检出率及总检出率均高于对照组（ P ＜0．05），观察组骨小梁结构出现模、线样征，骨髓水肿显示率均高于对照组（ P ＜0．05）。结论：MRI对早期股骨头坏死的检出率明显优于CT检查，可有效显示患者的典型征象，可作为早期股骨头坏死的首选检查方法。
