摘　　要：目的 探讨CT、MRI对早期股骨头缺血坏死的诊断效果。方法 回顾性纳入2022年9月至2023年9月于我院进行检查的77例疑似股骨头缺血坏死患者作为研究对象。患者均接受CT、MRI的检查,以患者临床症状、影像学、实验室检查的综合评估结果作为金标准,分析CT、MRI在早期股骨头缺血坏死中的诊断价值,并分析两种检查方法对于分期的诊断差异。结果 77例疑似患者最终有58例患者诊断为股骨头缺血坏死,另有19例其他骨关节疾病患者。CT在股骨头缺血坏死诊断中的灵敏度为81.03%,特异度为84.21%,符合率为81.82%。MRI在股骨头缺血坏死诊断中的灵敏度为94.83%,特异度为100%,符合率为96.10%。MRI检查对Ⅰ期患者的检出率为91.43%,高于CT检查的71.43%(P <0.05)。结论 MRI、CT在早期股骨头缺血坏死的诊断中均有较高的价值,其中MRI相较CT在Ⅰ期股骨头缺血坏死的诊断中具有一定优势,能增加早期确诊疾病的机会,有助于更早对疾病实施干预治疗。Objective To explore the diagnostic effect of CT and MRI on early ischemic necrosis of femoral head.Methods A total of 77 patients with suspected femoral head ischemic necrosis who were examined in our hospital from September 2022 to September 2023 were retrospectively included as study subjects.The patients were examined by CT and MRI,and the diagnostic value of CT and MRI in the early stage of femoral head ischemic necrosis was analyzed by taking the comprehensive evaluation results of clinical symptoms,imaging,and laboratory tests as the gold standard,and the diagnostic differences between the two imaging methods for staging were also analyzed.Results Fifty-eight of the 77 suspected patients were diagnosed with femoral head ischemic necrosis,and 19 patients with other osteoarthritic diseases.The sensitivity of CT in the diagnosis of femoral head ischemic necrosis was 81.03%,the specificity was 84.21%,and the compliance rate was 81.82%.The sensitivity of MRI in the diagnosis of femoral head ischemic necrosis was 94.83%,and the specificity was 100%,and the compliance rate was 96.10%.96.10%.The detection rate of MRI examination for patients with stage I was,91.43% higher than that of CT examination,71.43%(P<0.05).Conclusions MRI and CT have high value in the diagnosis of early ischemic necrosis of the femoral head,among which MRI has certain advantages compared with CT in the diagnosis of stage I ischemic necrosis of the femoral head,which can increase the chances of early diagnosis of the disease,and can help to implement the intervention of the disease at an earlier time.
