目的探讨多层螺旋CT血管成像(MSCTA)在颅内动脉瘤诊断中的应用。方法回顾性分析吉林油田总医院45例蛛网膜下腔出血患者的MSCTA检查,观察其原始图像及后处理图像。结果发现45例患者中共34例颅内动脉瘤,3例颅内动静脉畸形,2例烟雾病,其中颅内动脉瘤发生在颈内动脉16例,大脑前交通动脉7例,大脑中动脉5例,大脑前动脉3例,大脑后动脉2例,基底动脉1例;MSCTA可充分显示颅内动脉瘤的大小、位置、形态与周围解剖结构的关系。结论 MSCT在颅内动脉瘤诊断中有较高的应用价值,可以作为外科治疗颅内动脉瘤的筛选方法。
Objective To investigate the application of multislice CT angiography (MSCTA) in the diagnosis of intracranial aneurysms. Methods The MSCTA of 45 patients with subarachnoid hemorrhage in Jilin Oilfield General Hospital were retrospectively analyzed. The original images and post-processing images were observed. The results showed that in 45 patients, there were 34 cases of intracranial aneurysm, 3 cases of intracranial arteriovenous malformations and 2 cases of moyamoya disease. The intracranial aneurysms occurred in 16 cases of internal carotid artery, 7 cases of anterior communicating artery, 7 cases of middle cerebral artery 3 cases of anterior cerebral artery, 2 posterior cerebral artery and 1 basilar artery. MSCTA can fully display the relationship between the size, location and morphology of intracranial aneurysm and its surrounding anatomy. Conclusion MSCT has a high value in the diagnosis of intracranial aneurysms and can be used as a screening method for surgical treatment of intracranial aneurysms.
