摘要 目的:探讨多层螺旋CT(MSCT)及其图像后处理技术在肺栓塞诊断中的意义及价值。方法:应用多层螺旋CT机对80例肺栓塞病人行动脉增强扫描,并将图像进行多层面重建(MPR)、曲面重建(CPR)、容积再现(VR)、最大密度投影(MIP)技术重组再处理。结果:单纯行MSCT扫描发现肺动脉栓子776支,其中主动脉15支、左右肺动脉69支、叶动脉171支、段动脉389支、亚段动脉132支;经图像后处理技术重组后发现肺动脉栓子790支,其中主动脉15支、左右肺动脉69支、叶动脉171支、段动脉397支、亚段动脉138支。结论:图像后处理技术可以较单纯MSCT更为直观、形象、全面显示栓子的形态、部位、范围,二者结合使用,将更有利于血栓的检出、分型。
