目的探讨多层螺旋CT血管成像 技术(MSCTA)在脑出血早期诊断的应用价 值。方法 通过对患者进行螺旋CT平扫， 对45例脑出血患者进行临床诊断，将诊断 的结果与DSA全脑动脉造影检查结果进行 比较。结果 在45例脑出血患者中，通过 对其进行MSCTA检查，结果发现29例患者 为脑动脉瘤，9例患者为动静脉畸型，2 例患者为烟雾病，3例患者为静脉性血管 畸型，2例患者原因不明。病理检出脑动 脉瘤30例，SCTA显示动脉瘤29，检出率为 96.67 %，4例患者肿瘤位于颈内动脉颅内 段、9例患者肿瘤位于前交通动脉、4例患 者肿瘤位于大脑前动脉、3例患者肿瘤位 于椎基动脉、9例患者肿瘤位于大脑中动 脉。结论 血管CTA成像技术是一种安全、 无创、可靠的脑血管成像技术，可作为脑 出血早期诊断的首选方法。

Objective To investigate the multi slice spiral CT angiography (MSCTA) in the application value in the early diagnosis of cerebral hemorrhage. Methods Through spiral CT plain scan in 45 cases of patients, cerebral hemorrhage patients for clinical diagnosis, the results of whole brain angiography diagnosis result is compared with the DSA method. Results In 45 cases of cerebral hemorrhage patients, were examined by MSCTA on it, found that 29 patients with cerebral aneurysm, 9 patients with arteriovenous malformation, 2 cases of patients with moyamoya disease, 3 patients with venous vascular malformation, 2 cases of patients with unexplained. Pathological detection of cerebral aneurysm in 30 cases, SCTA showed aneurysm in 29, the detection rate was 96.67%, 4 cases of patients with tumors located in the intracranial segment of internal carotid artery in 9 patients, the tumors located in the anterior communicating artery, 4 cases of patients with tumors located in the anterior cerebral artery, 3 cases of patients with tumor in the vertebral basilar artery, 9 patients with tumor in the brain artery. Conclusion Vascular CTA imaging technique is a safe, no brain vascular imaging invasive, reliable and can be used as the preferred method for early diagnosis of cerebral hemorrhage.
