摘　　要：目的探讨320排CT诊断肋骨隐匿性骨折的价值。方法回顾性分析35例临床怀疑肋骨骨折,而数字化X线摄影显示为阴性的病例,进一步行320排螺旋CT扫描,并行重建后处理,分析所得图像。结果 35例数字化X线摄影均未见明确肋骨骨折,而320排CT检出81处骨折,其中单发骨折11例(31.4%),多发骨折24例(68.6%)。结论 320排CT显示肋骨无错位细微骨折优于数字化X线摄影,可作为肋骨隐匿性骨折的首选检查方法。Objective To investigate the value of 320-detector-row CT in diagnosing rib occult fracture.Methods 35 patients with clinical suspicion of rib fracture who had negative results of DR were studied using 320-detector-row CT.The images of two-dimensional and three-dimensional reconstruction were analyzed.Results 81 fractures were detected in 35 cases had no definite rib fractures in DR by using the 320-detector-row CT,including 11 cases with single fractures（31.4%）,24 patients with multiple fractures（（68.6）%）.Conclusion 320-detector-row CT is superior to DR imaging in displaying microfracture of rib,and it is the best method in diagnosing rib occult fracture.
