摘要
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。
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.
