多层螺旋CT在髋关节病变中的诊断价值

目的探究髋关节病变患者应用多层螺旋CT进行诊断的临床价值。方法将我院120例髋关节病变患者给予CT扫描,对其三维重建成像给予分析,观察患者病变立体形态与周围结构关系,跟常规X线结果实行对比。结果 X线检查的患者,漏诊误诊率为61.66%,其中骨折漏诊20例、结核漏诊10例、关节内骨碎片误诊19例、关节内骨碎片漏诊25例;CT扫描,漏诊误诊率为16.67%,其中骨折漏诊8例、结核漏诊5例、关节内骨碎片误诊4例、关节内骨碎片漏诊3例。两种检查方式数据比较,差异具有统计学意义(P0.05)。结论相较于常规X线有限的髋关节病变显示,CT三维重建成像技术可更直观地将病变以立体形态显示出来,可明确地显示复杂骨折粉碎的程度与移位,可作为手术入路与内固定的影像学指导。且相对于X线检查,CT检查对髋关节病变患者诊断更为精准,值得临床应用。

The Value of Multi-Slice Spiral CT in Diagnosis of Hip Joint Lesions

Objective To explore the clinical value of MSCT in the diagnosis of hip joint lesions. Methods CT scan was given to 120 cases of patients with hip joint lesions in our hospital, and the three-dimensional reconstruction images were analyzed. To observe the relationship between the three-dimensional shape of the lesion and the surrounding structures, and to compare with the routine X-ray results. Results The misdiagnosis rate of patients undergoing X-ray examination was 61.66%, among which 20 cases were missed diagnosis of fracture, 10 cases were missed diagnosis of tuberculosis, 19 cases were misdiagnosed of joint bone fragments, and 25 cases were missed diagnosis of joint bone fragments; The misdiagnosis rate of patients undergoing CT scan was 16.67%, among which 8 cases were missed diagnosis of fracture, 5 cases were missed diagnosis of tuberculosis, 4 cases were misdiagnosed of joint bone fragments, and 3 cases were missed diagnosis of joint bone fragments. To compare the two kinds of examination data, the difference was statistically significant(P<0.05). Conclusion Compared with conventional limited display of X-ray on hip joint lesions, CT three-dimensional reconstruction imaging technology displays three-dimensional shapes of lesions in more intuitive manner, may clearly display the degree and displacement of complex fracture, and may serve as an imaging guidance for surgical approach and internal fixation. And the diagnosis of CT examination on patients with hip joint lesions is more accurate when compared with that of X-ray, being worthy of clinical application.
