摘要: 目的 探讨基于 CT 血管造影( computertomographypulmonaryangiography , CTPA )的胸部高分辨率
计算机体层 X 线摄影术( high-resolutioncomputedtomography , HRCT )表现对肺栓塞的诊断价值。方法 回顾性
分析 73 例临床怀疑肺栓塞患者的 CTPA 及基于 CTPA 重建出的胸部 HRCT 图像,根据 CTPA 结果将所有病例分
为肺栓塞组及非肺栓塞组,对比分析 2 组 CTPA 及胸部 HRCT 图像,归纳肺栓塞差异具有统计学意义的影像学征
象。结果 CTPA 确诊肺栓塞(阳性组) 25 例和排除肺栓塞(阴性组) 48 例, 2 组年龄和性别差异无统计学意义;左、
右侧肺动脉栓塞支数差异无统计学意义;大部分栓子分布于肺段以下;中心性充盈缺损超过其他栓塞类型总和的 2
倍;肺栓塞组和非肺栓塞组最常见的胸部异常均为胸膜肥厚和实变影; HRCT 肺动脉高压提示肺栓塞的可能性约
为无肺动脉高压患者的 3.
29 倍,肺动脉高压对于肺栓塞的发生具有预测价值。结论 多排螺旋 CT 对于肺栓塞患
者的检查,具有快捷无创、敏感性高的特点;在进行 CTPA 检查时,同时重建出肺部 HRCT ,可以实时评估肺部有无
其他基础疾病,便于提高 CTPA 诊断价值,避免二次行胸部 CT 检查带来的额外辐射。

Abstract:  Objective To evaluatethe diagnostic value of high-resolution computed
tomography ( HRCT ) based on computertomography pulmonary angiography (
CTPA ) in
pulmonaryembolism ( PE ) .Methods Retrospectivelyanalyzed CTPA andthechest HRCT
