X线平片与多层螺旋CT对髋关节疾病的诊断价值对比

目的探讨X线平片与多层螺旋CT对髋关节疾病的诊断价值。方法选取2018年1月至2019年3月我院收治的髋关节疾病患者116例,患者均进行了X线平片与多层螺旋CT,收集患者影像学资料及临床资料,比较两种检查对髋关节疾病误诊率、漏诊率。结果X线平片对髋关节骨折、股骨头坏死、髋关节结核诊断准确率分别为80.28%、75.86%、68.75%;螺旋CT对髋关节骨折、股骨头坏死、髋关节结核诊断准确率分别为95.77%、100.00%、100.00%,明显优于X线平片检查,差异有统计学意义(P<0.05);螺旋CT仅出现骨折漏诊、关节内碎片漏诊各1例(0.86%),髋关节疾病漏诊误诊合计发生率为1.72%;X线平片骨折漏诊、结核漏诊、关节内碎片漏诊、关节内碎片误诊率分别为6.03%、3.44%、4.31%、3.44%,漏诊误诊合计发生率为17.24%,高于螺旋CT检查,差异有统计学意义(P<0.05);多层螺旋CT可有效、全面显示股骨头缺血性坏死、髋关节结核、股骨头骨折典型影像学征象。结论X线平片、多层螺旋CT均可有效显示不同髋关节疾病的图像表现,多层螺旋CT对髋关节疾病诊断准确率优于X线平片,漏诊误诊率低。

Diagnostic Value of X-ray Plain Film and Multi-slice Spiral CT in the Diagnosis of Hip Joint Disease

Objective To explore the diagnostic value of plain X-ray film and multi-slice spiral CT in diagnosing of hip joint disease.Methods 116 patients with hip joint disease admitted to our hospital from September 2018 to March 2019 were enrolled.All patients underwent plain X-ray film and multi-slice spiral CT.The patient’s imaging data and clinical data were collected,and the rate of misdiagnosis and missed diagnosis of hip joint disease were compared between the two examinations.Results The diagnostic accuracy of X-ray plain film for hip fracture,femoral head necrosis,and hip joint tuberculosis was80.28%,75.86%,and 68.75%.The diagnostic accuracy of spiral CT for hip fracture,femoral head necrosis and hip joint tuberculosis was 95.77%,100.00%,100.00%,which was significantly better than that of plain X-ray film.The difference was statistically significant(P<0.05).In spiral CT,only 1 case(0.86%)with a missed diagnosis of fractures and 1 patient with a missed diagnosis of intra-articular fragments occurred.The total incidence of misdiagnosis of missed diagnosis for the hip joint disease was 1.72%.The rate of missed diagnosis of fractu re missed diagnosis of tuberculosis,missed diagnosis of intra-articula r fragments,misdiagnosis rate of intra-articular fragments in plain X-ray film were 6.03%,3.44%,4.31%,3.44%,and the total incidence of misdiagnosis was 17.24%,higher than those of spiral CT exa mination.The difference was statistically significant(P<0.05).Multi-slice spiral CT ca n effectively and co m p rehensively display the typical imaging signs of avascular necrosis of the femoral head,tuberculosis of the hip joint,and femoral head fracture.Conclusion X-ray plain film and multi-slice spiral CT can effectively display the image cha racteristics of different hip joint diseases.The diagnostic accu racy of multi-slice spiral CT for the hip joint disease is better than that of X-ray film,and the rate of misdiagnosis is low.
