目的探讨CTA头部血管成像技术对颅内血管性疾病的诊断价值及其质量控制技术要点。方法选取DSA诊断为颅内血管性病变的患者51例，进行CTA头部血管成像扫描，根据OTA诊断的检出率以及图像品质分析其临床诊断价值和质量控制技术要点。结果本组51例患者均获得清晰图像，其中达Ⅲ级18例、达Ⅳ级标准41例；CTA诊断出动脉瘤30例、动脉狭窄11例，动脉畸形6例，静脉畸形3例，脑血管病诊出率为49例（96.1％）。结论cTA头部血管成像技术对颅内血管性疾病诊断价值较高；通过适当控制扫描条件与参数，选择合适的图像后处理方法，可进一步提高其诊断水平。

Objective To discuss the CTA head vascular imaging in the diagnosis of intracranial vascular disease value and its quality control points.Methods The hospital were selected, DSA diagnosis of intracranial vascular lesions in patients with 51 cases, head of CTA vascular imaging scans, according to the detection rate of CTA diagnosis and image quality analysis of the clinical diagnosis value and technical key points of quality control.Results All 51 patients were get clear image, including theⅢ grade 18 cases,Ⅳlevel standard 41 cases;CTA aneurysm diagnosed 30 cases, 11 cases of artery stenosis, artery malformation 6 cases, venous malformations (3 cases), cerebrovascular disease diagnosis rate was 96.1%(n=49). Conclusion CTA head vascular imaging technology to higher value in diagnosing intracranial vascular disease;Scanning through proper control conditions and parameters, choose the right image post-processing method, can further improve the level of the diagnosis.

目的：分析比较CT血管成像（CTA）、磁共振血管造影（MRA）及数字减影，血管造影（DSA）在颅内动脉瘤和脑血管畸形临床诊断中的应用价值。方法 选取2012－01～2013－12间在我院神经内科住院且需进行脑血管检查的83例患者为研究对象，并进行CTA、MRA、DSA检查，比较不同方法对脑血管疾病的诊出率以及发病部位的诊断情况。结果 三种诊断方式对脑血管疾病检出的敏感性无明显差异（P＞0．05）；三种诊断方式对脑血管疾病检出部位无明显差异（P＞0．05），三种检查方式均可用于不同类型脑血管畸形诊断，诊出率无明显差异（P＞0．05），经比较，MRA对小型畸形检出效果较差，CTA对重型畸形检出效果较差。结论 CTA、MRA及DSA对脑血管疾病诊断效果无明显差异，在临床应用时，应综合考虑检查方式利弊，并注意结合患者实际情况进行选择。
