摘要
目的探讨单排螺旋CT多方位扫描在腕关节外伤中的应用价值。方法选择腕关节外伤患者76例,全部病例均行X线片以及CT横断位、冠状位及矢状位扫描,对比分析单排螺旋CT不同扫描方位对骨折和关节关系的显示情况。结果共发现骨折98处,失稳或脱位10处。X线片与CT横断位、冠状位、矢状位对腕骨骨折与腕骨不稳或脱位的检出率比较,差异均有统计学意义(χ2=4.248、9.960、14.430;P=0.035、0.002、0.000)。CT横断位与冠状位及横断位与矢状位的检出率比较,差异无统计学意义(χ2=3.070,P=0.251;χ2=1.260,P=1.030)。结论 CT检查时,在横断面扫描成像的基础上,适当补充CT矢状位或冠状位扫描,从多方位、多角度展示腕部诸骨的解剖关系,在图像显示中相互补充,能提高细微骨折及失稳或脱位等的检出率。
Objective To study the value of single row spiral CT in multi-aspect scanning in patients with traumatic wrist joint .Methods A total of 76 patients with wrist trauma underwent conventional X-ray and spiral CT （including transverse plane ,coronal plane and sagittal plane）examinations .Different azimuth imaging data acquired in all patients were compared .Results A total of 98 fractures and 10 dislocations were found .There were significant differences on the detection rates between X-ray and transverse plane ,coronal plane and sagittal plane（χ2 = 4 .248 , 9 .960 ,14 .430 ;P= 0 .035 ,0 .002 ,0 .000） .There were no significant differences on the detection rates between trans-verse plane and coronal plane ,between transverse plane and sagittal plane （χ2 = 3 .070 ,P = 0 .251 ;χ2 = 1 .260 ,P=1 .030） .Conclusion Different scanning azimuth could supplement each other ,improve the accuracy of diagnosis ,and provide a more comprehensive imaging basis for clinical diagnosis .
