32层螺旋CT三维重组在胸部外伤诊断中的价值

目的探讨32层螺旋CT三维重建在胸部外伤诊断中的临床应用。方法搜集112例胸部外伤的病例,全部病例均行X线摄片及32层螺旋CT扫描,并以1.25mm层厚行多平面容积重组(MPR)及容积再现法(VR)图像后处理,观察分析骨折的位置、数量及邻近组织、脏器的情况。结果在112例病例中,检查发现肋骨骨折98例,胸腰椎压缩骨折2例,胸骨骨折11例,胸椎棘突骨折3例,肩胛骨骨折16例。X线平片共发现肋骨骨折82例,胸骨骨折4例,肩胛骨骨折3例,肺挫伤21例,血气胸2例。结论 32层螺旋CT三维重组及图像后处理技术的联合应用,能对胸部外伤患者作出快速、准确的诊断,对判断胸部外伤骨折及邻近组织、脏器损伤,指导临床医生对患者进行及时、有效的救治,有较高的临床应用价值。

The evaluation of 3D reconstruction with MSCT in the diagnosis of chest trauma fractures

Objective To investigate the clinical application of 3D reformation technique with in the diagnosis of Thoracic injury.Methods 112 patients of Thoracic injury were enrolled in this sdudy.Radiography and 32-slice spiral CT were used with slice thickness as 1.25 mm and post processing technique of multi-planar reformation and volume reformation the fracture location,quantity and neighboring tissue,organ of the situation were observed and analyzed.Results Of the 112 patients,there were rib fractures in 98 cases,thoracic and lumbar compression fracture in 2 cases of sternal fracture in 11 cases,thoracic spinous process fracture in 3 cases,scapula fracture in 16 cases.X-ray rib fractures were found in 82 cases,sternal fracture in 4 cases,scapula fracture in 3 cases,pulmonary contusion in 21 cases,blood pneumothorax in 2 cases.Conclusion 32-slice spiral CT three-dimensional reorganization in combination with image processing technology in patients with chest trauma can make quick,accurate diagnosis,determine chest trauma fracture and adjacent tissue,organ damage,guide clinicians for treating patients in a timely,effective manner,which has a high clinical value.
