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
