螺旋CT血管造影及三维重建在脑血管疾病中的临床应用

目的：探讨螺旋CT血管造影（Spiral CT angiograply SCTA)及三维重建的新技术，在脑血管病中的应用价值，方法：对26例脑血管患者进行了SCTA检查和三维重建，三维重建采用最大强度投形（MIP）或表面示意图法（Sutface Rendeling)，其中颅内动脉瘤13例，脑血管畸形6例，自发性颅内出血5例，脑缺血性疾病2例，本组有23例行数字减形血管造影（DSA）检查，且与CTA结果对照，结果：除3例末行DSA检查的患者，1例多发性动脉瘤CTA漏检2个小动脉瘤外，22例CTA的结果与DSA相同。CTA在描绘毗邻骨结构以及脑血管三维结构上优于DSA，结论：SCTA是一种简单，快捷，有效的无创伤性脑血管成像术，在某种程度上可替代DSA或创伤性的脑血管造影。

Clinical use of Spiral CT Angiogram (SCTA) and 3D Reconstruction in Cerebrovascular Diseases

This paper intend as to inquire into spiral CT angiogram (SCTA) and the new technology of 3D reconstruction. in the use of cerebrovascular diseases. We examined 26 cases of cerebrovascular. Diseases by CTA and 3D reconstruction. 3D reconstruction uses Maximum Intensity Projection (MIP) or surface Rendering. There was 13 cases of intracranial aneurysm, 6 cases of cerebrovascular Malformation, 5 cases of spontaneous intracranial hemorrhage and 2 cases of cerebral ischemia, This group contained 23 cases by DSA and was contrasted with the ones by CTA. The result of 22 cases by CTA was the same as the ones by DSA except that 3 cases weren't used DSA and 1 cases of multiple aneurysm wasn't found 2 little aneurysm by CTA. CTA is superior to DSA in describing the bone structure and the cerebrovascular 3D structure. SCTA is a simple, quick, valuable cerebrovascular photography with no wound. It can replace DSA or wounded angiogram of the head.
