[摘要] 目的 研究CT与核磁共振应用在股骨头坏死中的诊断效果，并分析两组患者对诊断结果的满意度。 方法 方便选取该院收治的42例股骨头坏死患者进行研究，共84髋，病例的选取时间为2014年8月—2016年6月，按照随机数字表法将其分为研究组和对照组，每组患者21例，42髋，对照组患者行CT检查，研究组患者行核磁共振检查，比较两组患者的诊断效果，分析两组患者对诊断结果的满意结果。 结果 研究组未检出數1髋，检出41髋，检出率为97.62%，与对照组相比（检出29髋，检出率为69.05%）差异有统计学意义（χ2=12.342 9，P=0.000 4），研究组十分满意6例，比较满意9例，基本满意5例，对照组十分满意3例，比较满意4例，基本满意6例，研究组总满意度为95.24%，显著高于对照组（61.90%），组间差异有统计学意义（χ2=6.929 3，P=0.008 4）。结论 核磁共振诊断股骨头坏死患者的诊断效果明显，显著优于单独应用CT检查的结果，且具有对人体的辐射小的特点，能够给患者的病变部位组织提供纤细的病变与解剖信息诊断率较高，准确获取所需多参数的信息数据，值得临床应用探索。

[Abstract] Objective To study the diagnostic effects of CT and MRI in femoral head necrosis and to analyze the satisfaction of the two groups in the diagnosis. Methods A total of 42 patients with femoral head necrosis treated in the hospital were studied. A total of 84 hips were convenient selected from August 2014 to June 2016. They were divided into study group and control group according to the random number table method. Each group had 21 patients and 42 hips. The control group underwent CT examination. The study group underwent MRI examination. The diagnostic effects of the two groups were compared. The satisfactory results of the two groups were analyzed. Results There were no 1 hips detected in the study group and 41 hips were detected. The detection rate was 97.62%. Compared with the control group （detected 29 hips， the detection rate was 69.05%）， the difference was significant（χ2=12.342 9， P=0.000 4）， the study group was very satisfied with 6 cases， 9 cases were satisfactory， 5 cases were basically satisfactory， the control group was very satisfied with 3 cases， 4 cases were satisfactory， 6 cases were basically satisfactory. The total satisfaction rate of the study group was 95.24%， which was significantly higher than the control group （61.90%）， the difference between the groups was significant， with statistical significance（χ2= 6.929 3， P=0.008 4）. Conclusion The diagnosis of femoral head necrosis in patients diagnosed by nuclear magnetic resonance has obvious diagnostic effect. It is significantly better than the results of single-use CT examination. It has the characteristics of small radiation to the human body. It can provide the patient with fine lesions and anatomical information， accurate access to the required multi-parameter information data， which is worth exploring in clinical applications.
