| 摘 要： | 目的探讨多排螺旋CT增强扫描血管三维重建技术（MSCTA）在急性肺动脉栓塞诊断中的应用价值。方法回顾性分析应用MSCTA方法确诊20例患者的影像资料,观察血栓累及的部位、表现形式及其他改变。结果急性肺动脉栓塞20例累及动脉及其分支89支,其CT表现直接征象包括：中心性充盈缺损10例、部分性充盈缺损3例、附壁性充盈缺损4例、完全阻塞性充盈缺损3例;间接征象包括肺门动脉增宽、局限性肺纹理稀疏、肺梗死、胸腔积液和心包积液等。（MSCTA）图像诊断显示阳性的为19例,阳性率为95%。与临床诊断符合为18例,临床诊断符合率为90%。结论多排螺旋CT增强扫描血管三维重建技术（MSCTA）是一种安全、快捷、有效、无创性的诊断检查方法,且诊断率较高,在急性肺栓塞诊断中具有重要价值。

| Abstract: | Objective To explore the value of multi-slice spiral CT angiography(MSCTA) by 3-dimensional(3D) reconstruction in diagnosing acute pulmonary embolism.Methods The image features of 20 patients with acute pulmonary embolism confirmed by MSCTA were analyzed retrospectively,including the location and the appearance of thrombus and other complicated changes.Results There were 89 arteries and its branches involved in all 20 cases.Direct signs represented as all kinds of filling defect,such as central filling defe... |
