【摘要】：目的探讨多层螺旋CT(multislice spiral computed tomography,MSCT)骨三维重建在诊断肋骨及肋软骨骨折中的应用价值。方法选取43例胸部外伤患者为研究对象,均行多层螺旋CT扫描,运用容积重建(volume rendering,VR)、最大密度投影(maximum intensity projection,MIP)、多平面重建(multi planar reconstruction,MPR)三维重建肋骨及肋软骨,并与常规CT平扫对比,分析MSCT三维重建的诊断优势。结果 43例肋骨骨折,共122根;其中单发骨折占30.23%,多发骨折占69.77%;肋骨骨折腋段较为常见,占95.65%;15例肋软骨骨折,共23根;MSCT检出24例外伤后并发症。MSCT三维重建技术诊断肋骨及肋软骨骨折的准确率为98.36%、95.65%,显著高于CT平扫的72.95%、13.04%,差异具有统计学意义(P0.05)。结论 MSCT临床诊断肋骨及软骨骨折的准确率较高,可作为诊断该疾病的理想影像学方法。
[Abstract]:Objective to evaluate the value of 3D reconstruction of multislice spiral CT (multislice spiral computed tomography-MSCT (MSCT) in the diagnosis of rib and costal cartilage fractures. Methods Forty-three patients with thoracic trauma were studied. Three dimensional reconstruction of rib and costal cartilage was performed by volume rendering VR, maximum density projection (maximum intensity projection and multiplanar reconstruction of (multi planar reconstruction.These images were compared with conventional CT scans. The diagnostic advantages of MSCT 3D reconstruction were analyzed. Results there were 122 rib fractures in 43 cases, in which single fracture accounted for 30.23 and multiple fractures accounted for 69.77. The axillary segment of rib fracture was more common, accounting for 95.6555 cases of costal cartilage fracture. The accuracy of MSCT in diagnosing fracture of rib and costal cartilage was 98.36 and 95.65, which was significantly higher than that in plain CT scan (72.95 and 13.04). The difference was statistically significant (P0.05). Conclusion MSCT is an ideal imaging method for the diagnosis of rib and cartilage fractures.
