目的探讨螺旋CT三维重建在腕关节骨折中的诊断价值及实际应用。方法选择我院2011(2009)年2月至2012年2月47例腕关节骨折患者的螺旋CT三维重建资料进行回顾性分析,47例患者在进行CT诊断前均行X平片检查,观察螺旋CT三维重建的诊断价值。结果螺旋CT共检出舟骨骨折42例,大多骨骨折2例,三角骨骨折2例,月骨周围脱位11例,X平片检出舟骨骨折35例,大多骨骨折1例,三角骨骨折2例,月骨周围脱位11例,两种方法比较差异具有显著性,有统计学意义P<0.05。比较螺旋CT不同重建模式影像结果,冠状位为主任意斜位成像(MPR)的检出率最高,其次为轴位图像,排列顺位依次是MPR、轴位图像、MIP与SSD。结论螺旋CT三维重建可对腕关节骨折患者准确定性和定位,为伤情的确诊及治疗方案的确定提供科学的指导依据。
Objective To investigate the diagnostic value and practical application of spiral CT three-dimensional reconstruction in the diagnosis of wrist fracture. Methods A retrospective analysis of 47 patients with fractures of the wrist from February 2011 to February 2012 in our hospital was performed. X-ray examination was performed in 47 patients before CT diagnosis. The spiral Diagnostic Value of Three Dimensional CT Reconstruction. Results Spiral CT were detected in 42 cases of scaphoid fracture, most of the fracture in 2 cases, triangular fracture in 2 cases, 11 cases of lunate bone dislocation, X-ray detection of scaphoid fracture in 35 cases, most of the fracture in 1 case, the triangular bone There were 2 cases of fracture and 11 cases of dislocation around the lunate. There was significant difference between the two methods (P <0.05). Comparing the images of different reconstruction modes of spiral CT, the highest incidence of coronary angiography (MPR) was detected, followed by the axial images, followed by MPR, axial images, MIP and SSD. Conclusion Three-dimensional reconstruction of spiral CT can accurately identify and locate the patients with wrist fracture, providing a scientific basis for the diagnosis of the injury and the determination of treatment options.
