目的：评价ＣＴ脑血管造影临床应用价值。材料和方法：ＣＴ脑血管造影６２例，其中脑动脉瘤２２例，脑动静脉畸形６例，脑肿瘤５例，脑内感染性肉芽肿性病变６例，颈内动脉海绵窦瘘２例，头皮血管瘤１例，正常２０例。其中２２例脑动脉瘤，６例脑动静脉畸形及２例颈内动脉海绵窦瘘还进行了ＤＳＡ检查。结果：６２例ＣＴＡ均能显示１～４级脑动脉结构，有时甚至显示５级脑动脉结构。２２例脑动脉瘤及６例脑动静脉畸形均经ＣＴＡ检出，其诊断结果与ＤＳＡ一致。５例脑肿瘤可见明显“肿瘤染色”。结论：ＣＴＡ为非损伤性血管检查方法，安全简便，其阳性检出率高，具有重要诊断价值和意义
Objective: To evaluate the clinical value of CT angiography. Materials and Methods: CT angiography in 62 cases, of which 22 cases of cerebral aneurysm, cerebral arteriovenous malformation in 6 cases, brain tumor in 5 cases, 6 cases of intracranial infectious granulomatous disease, 2 cases of internal carotid cavernous fistula, 1 case of scalp hemangioma, 20 cases of normal. DSA was also performed in 22 cases of cerebral aneurysm, 6 cases of cerebral arteriovenous malformation and 2 cases of internal carotid cavernous fistula. Results: Sixty-two CTAs showed grade 1 to 4 cerebral arteries and sometimes even grade 5 cerebral arteries. 22 cases of cerebral aneurysm and 6 cases of cerebral arteriovenous malformation were detected by CTA, the diagnostic results consistent with the DSA. Five cases of brain tumors showed obvious “tumor staining.” Conclusion: CTA is a noninvasive vascular examination method, which is safe and simple, and has a high positive detection rate, which is of great diagnostic value and significance
