摘　　要：目的研讨股骨头坏死患者实施CT与MR技术诊断的临床价值。方法选取我院收诊于近两年的50例股骨头坏死患者作为实验对象,对患者实施CT、MR技术检查并评估诊断结果。结果 CT与MR在Ⅲ期、Ⅳ期股骨头坏死的检出率上对比,无统计学意义(P>0.05),但与CT比较,MR对Ⅰ-Ⅱ期股骨头坏死的检出率、总检出率显著提高,比较有统计学意义(P<0.05)。在早期(Ⅰ-Ⅱ期)股骨头坏死的诊断灵敏度、漏诊率方面,MR均优于CT,比较有统计学意义(P<0.05),MR与CT的特异度与误诊率对比,无统计学意义(P>0.05)。结论 MR对股骨头坏死的整体诊断效果优于CT,值得推荐。Objective To study clinical value of CT and MR diagnosis on femoral head necrosis. Methods Choose 50 cases femoral head necrosis patients admitted to our hospital during past two years as experimental subjects, examine them with CT and MR techniques and evaluate diagnostic effect. Results No significant difference showed between CT and MR in detection rate of stage III and IV femoral head necrosis(P>0.05), but compared with CT, detection rate and total detection rate of stage I-II femoral head necrosis of MR was significantly higher, with statistical significance(P<0.05). MR showed better effect in diagnostic sensitivity and missed diagnosis rate of early stage(stage I-II) femoral head necrosis than CT,(P< 0.05). Specificity and misdiagnosis rate showed no significant difference between MR and CT(P>0.05). Conclusion MR has better effect than CT in overall diagnosis of femoral head necrosis, which is worth recommending.
