X光片和多排螺旋CT、MR对骨关节创伤的诊断对比

X-ray, Multi-slice Spiral CT and MR in the Diagnosis of Bone and Joint Trauma

目的:分析对比X光片和多排螺旋CT、MR对骨关节创伤的诊断效果。方法:回顾性分析我院在2017年4月-2018年5月接诊的43例骨关节创伤患者,分别进行东芝64排螺旋CT扫描,并用X光片(A组)、三维重组技术处理图片(B组)和动态MR(C组),对比三组骨关节骨折的检出率。结果:60例患者经最后确诊的骨折有70处,A组应用X光片检出51处,检出率为72.9%;B组采用多排螺旋CT三维重组技术检出67处,检出率为95.7%;C组采用动态MR检出70处,检出率为100%。对比三组,差异有统计学意义,P<0.01。结论:动态MR可有效提高骨折的诊断效果,降低漏诊和误诊率,在临床上值得推广应用。

Objective:To analyze and compare the diagnostic effects of X-ray,multi-slice spiral CT and MR on bone and joint trauma.Methods:A retrospective analysis of 43 cases of bone and joint trauma patients received in our hospital from April 2017 to May 2018 was conducted.Toshiba 64-slice spiral CT scan was performed,and X-ray(group A),three-dimensional reconstruction technology images(group B)and dynamic MR(group C)were processed by three-dimensional recombination technology,and the detection rates of bone and joint fractures in the three groups were compared.Results:70 fractures were finally diagnosed in 60 patients,and 51 fractures were detected by X-ray in group A with detection rate of 72.9%;67 fractures were detected by multi-row spiral CT three-dimensional reconstruction technology in group B with detection rate of 95.7%;and 70 fractures were detected by dynamic MR in group C with detection rate of 100%.The difference between the three groups was statistically significant(P<0.01).Conclusion:Dynamic MR can effectively improve the diagnosis of fracture and reduce the rate of missed diagnosis and misdiagnosis.
