64排128层螺旋CT肺动脉CTA对肺动脉栓塞的诊断价值探讨

目的:分析螺旋CT血管造影(CTA)诊断肺动脉栓塞的临床效果。方法:选取我院收治的35例肺动脉栓塞患者,纳入时间为2015年12月—2017年12月。利用64排128层螺旋CT扫描仪,对患者进行常规扫描和CTA增强扫描,观察诊断结果,分析影像学特征。结果:35例患者中,CTA诊断阳性率为94.3%,高于CT诊断的68.6%,差异有统计学意义(P <0.05)。肺动脉栓塞位于左肺动脉11例、右肺动脉14例、叶动脉6例、段动脉4例;栓塞类型:偏心性13例、中心性10例、附壁性8例、完全性4例。结论:CTA诊断肺动脉栓塞效果优于常规CT,具有安全便捷的优势,可以作为临床治疗和预后评估的依据。
