摘要
目的探讨64层螺旋CT对肺动脉栓塞的诊断价值。方法搜集本院2006年7月～2010年10月25例患者,均行64层螺旋CT平扫及肺动脉CTA检查,并采用MIP(最大密度投影)、MPR(多平面重建)及VR(三维重建)对原始图像进行后处理。结果 25例CT图像均能对栓子的形态、密度、栓塞部位、范围及局部狭窄程度充分显示,CT表现为肺动脉内不规则的斑块状及附壁样充盈缺损,斑块周围有或无高密度对比剂包绕。结论 64层螺旋CT是目前临床诊断肺动脉栓塞最有效的方法之一。
Objective To study the cllnieal value of 64-slice helical CT pulmonary artery angiography in detection of pulmonary embolism. Methods Twenty-five patients with PE underwent 64-slice helical CT angiography （ CTA ）, two-dimensional and three- dimensioual reformation were performed in all cases including maximum intensity projection （ MIP ）, multiplanar reconstruction （ MPR ） arid volume rendering （ VR ）. All the data of CTA were retrospectttvely analysed. Results 64-sliee-helieal CT clearly showed the sites, extensions and stenosed lumens of PE in all patients. On CTA images, PE lesions appeared as iutraluminal irregular-plaque shape and adhered-mural filling defects whose periphery was probably encased by the contrast medium with hyperdensity. Conclusion 64- slice spiral CT angiography is one of the most effective and non-invasive imaging modalities in the diagnosis of pulmonary embolism.
