摘要
目的:分析探讨MSCT容积扫描及后重建技术在诊断肋骨隐匿性骨折中的临床应用及价值。材料与方法:对64例有明确胸部外伤史并经DR摄片可疑骨折或无明显异常的患者行MSCT容积扫描,采用多平面重组(MPR)、最大密度投影(MIP)、曲层重组(CPR)及容积重建(VRT)等后重建技术,了解有无肋骨骨折及显示骨折情况。结果:64例中39例DR摄片可疑骨折48处,MSCT诊断骨折38例、50处,1例无明显异常;25例DR摄片无明显异常患者,MSCT诊断骨折9例、12处。结论:MSCT容积扫描后重建技术能多层面显示肋骨结构,更好、更完整的显示隐匿性肋骨骨折,对肋骨骨折的诊断具有较高临床应用价值。
Purpose： This paper is dedicated to the analysis of the clinical application and value of MSCT volume scanning and after-treatment reconstruction techniques in diagnosing occult fracture.Materials and Methods： 64 patients,with definite chest trauma and whose DR Chest radiography given MSCT volume scanning.After-treatment techniques,such as MPR（multiplanar reconstruction）,MIP（Maximum intensity projection）,CRP（Curved planar reconstruction）,and VRT（volume rendering technique）,were employed to check and display whether fractures exist in the ribs and what the situation is.Results： Being able to give a multiplanar display of the rib structure,hence a better and more complete revelation of occult fractures,MSCT volume scanning and after-treatment reconstruction techniques proved to be of high clinical values in the diagnosis of rib fractures.Conclusion： MSCT,Image reconstruction,rib fracture,Occult fracture.
