【摘要】 目的探讨64排螺旋CT肺动脉成像在诊断肺栓塞中的临床应用价值。方法应用64排螺旋CT对27例临床上拟诊为肺栓塞患者进行肺动脉造影,并将图像进行容积再现(VR),最大密度投影(MIP),多平面重组(MPR)。结果64排螺旋CT肺动脉成像可充分观察到肺动脉血栓的大小、分布及范围,27例患者发现完全闭塞14支,附壁性充盈缺损36支,中心性充盈缺损12支,不规则性充盈缺损62支。结论64排螺旋CT血管成像是一种快捷、方便、安全、可靠、无创的诊断方法,在肺动脉栓塞的诊断及治疗中发挥重要的作用。更多还原

【Abstract】 Objective To investigate the clinical value of 64-slice spiral CT pulmonary angiography in the detection of pulmonary embolism.Methods 27 patients clinically suspected for pulmonary embolism were examined with the 64-slice spiral CT pulmonary angiography.The images underwent reconstruction with volume rendering(VR),maximum intensity projection(MIP)and multiplanar reconstruction(MPR) methods.Results 64-slice spiral CT pulmonary angiography could accurately show the location and the size of thrombus.Complete embolism was found in 14 vessels,mural filling defect in 36 vessels,central filling defect in 12 vessels and irregular filling defect in 62 vessels.Conclusion 64-slice spiral CT pulmonary angiography is quick,highly sensitive and noninvasive for the diagnosis of the pulmonary embolism,and it plays an important role in the diagnosis and treatment of pulmonary embolism.更多还原
