目的：探讨颈胸部螺旋ＣＴ血管成像（ＳＣＴＡ） 的合理检查技术及临床应用价值。方法：５６ 例颈、胸部ＳＣＴＡ病例，其中，２１例为血管性疾病，３５ 例为正常血管结构。均采用ＳＣＴ容积增强扫描，传输到工作站后处理成像，获得血管的三维（３Ｄ） 、四维（４Ｄ）及多平面重组（ＭＰＲ） 图像。结果：２１ 例血管病变３Ｄ、４Ｄ及ＭＰＲ图像，可直观、立体、多角度观察管腔及管壁形态，并显示感兴趣血管的立体结构及与周围组织的关系。结论：ＳＣＴＡ是有效的无创伤性血管成像技术，能准确地诊断颈、胸部血管病变，对指导手术有重要意义。
Objective: To explore the reasonable examination technique and clinical value of cervical and thoracic spiral CT angiography (SCTA). Methods: Fifty-six cases of SCTA in the neck and chest were selected. Among them, 21 cases were vascular diseases and 35 cases were normal vascular structures. SCT volume-enhanced scanning was performed and transmitted to the workstation for post-processing imaging to obtain three-dimensional (3D), four-dimensional (4D) and multiplanar reconstruction (MPR) images of blood vessels. Results: The 3D, 4D and MPR images of 21 cases of vascular lesions were observed visually, stereoscopically and multi - anglely to observe the morphology of the lumen and the wall of the vessel and to reveal the relationship between the three - dimensional structure of the vessel of interest and the surrounding tissues. Conclusion: SCTA is an effective noninvasive vascular imaging technique, which can accurately diagnose the cervical and thoracic vascular diseases and is of great significance for guiding the operation.
