【摘要】目的：分析CT与磁共振技术在股骨头坏死诊断中的应用价值。方法：筛比分析我院于2019年1月—2022年12月期间收治的股骨头坏死患者，选择其中50例参研，应用磁共振与CT两种方式进行诊断，比对两组精确度、对股骨头坏死分期的诊断结果、技术征象检出情况以及检验灵敏度与特异度。结果：磁共振组的精确度更高、股骨头坏死分期诊断更准确、征象检出概率高于CT组、灵敏度相对更高、特异度更低。两组比对差异显著（P<0.05），磁共振组显著更优。结论：磁共振技术相较于CT检验，对诊断股骨头坏死更具有帮助作用，建议临床参考应用。

【Abstract】Objective： To analyze the application value of CT and magnetic resonance technology in the diagnosis of femoral head necrosis. Methods： A screening analysis was conducted on patients with femoral head necrosis admitted to our hospital from January 2019 to December 2022. A total of 50 eligible patients were selected and invited to participate in the study. Magnetic resonance imaging and CT were used for diagnosis， and the accuracy of the two testing methods， diagnostic results for staging of femoral head necrosis， detection of technical signs， sensitivity and specificity of the tests were compared. Results： The magnetic resonance group had higher accuracy， more accurate diagnostic results for the staging of femoral head necrosis， higher detection probability of the three groups of signs than the CT group， relatively higher sensitivity， and lower specificity than the control group. The difference between the two groups was significant（P<0.05）， and the magnetic resonance group was significantly better. Conclusion： Magnetic resonance technology is more helpful in diagnosing femoral head necrosis compared to CT examination， and it is recommended for clinical reference.

股骨头坏死是病理演变过程，骨小梁结构在应力作用下发生变化，机体针对损伤的骨组织自行修复的过程就叫做股骨头坏死[1-2]。骨组织虽能自我修复，但若发病诱因没能被解决，就会导致损伤到修复的过程不断循环，股骨头结构出现塌陷、增生等，下肢功能受损[3-4]。随着疾病的发展行动能力下滑，若能在早期诊出股骨头坏死，展开治疗，就能有效改善患者病症，加快康复进展[5]。本研究就此分析CT与磁共振技术在股骨头坏死诊断中的应用价值。

1.1 一般资料

筛比分析我院临床于2019年1月—2022年12月期间收治的股骨头坏死患者，选择其中符合条件者共50例邀请参研，男26例，女24例，年龄42～65岁，平均年龄（51.63±6.46）岁，病程4～9个月，平均病程（6.81±1.47）个月，股骨头坏死：I期15例，Ⅱ期9例，Ⅲ期19例，Ⅳ期7例，均接受磁共振與CT两种诊断手段。经比对，确认两组除诊断方式不同外基础数据无差异，数据结果具备临床参考价值，全部共50例参研患者及其家属均对此知情。……
