目的:分析多层螺旋CT血管造影技术(MSCTA)在颅内自发性出血诊断中的成像特点,以提高MSCTA对颅内自发性出血病因分析的检出率。方法:回顾性分析164例颅内出血患者的多层螺旋CT影像资料,根据MSCTA成像特点,分析评价MSCTA在颅内自发性出血病因中的影像价值。结果:在164例患者中,动脉瘤合并出血者37例;血管发育不良伴出血者48例;动静脉血管畸形继发出血者13例;高血压合并脑动脉粥样硬化,继发出血者49例;白血病颅内浸润继发出血者3例;脑转移瘤伴出血者5例;凝血机制障碍继发颅内出血者2例;原因不明出血者7例。治疗前MSCTA检查明确出血原因者总计132例。MSCTA诊断与最终病理结果符合率达80.5%。结论:MSCTA能够作为颅内自发性出血的一种筛查手段,可为临床明确自发性颅内出血提供有效的影像学诊断依据。
Objective: To analyze the imaging features of MSCTA in the diagnosis of intracranial spontaneous hemorrhage and to improve the detection rate of MSCTA on the etiology of intracranial spontaneous hemorrhage. Methods: A retrospective analysis of 164 cases of intracranial hemorrhage in patients with multi-slice spiral CT imaging data, according to the characteristics of MSCTA imaging, analysis and evaluation of MSCTA in the etiology of intracranial hemorrhage in the image value. Results: Of the 164 patients, 37 had aneurysm hemorrhage, 48 had vascular dysplasia with hemorrhage, 13 had hemorrhage secondary to arteriovenous malformations, 13 had hypertension with cerebral atherosclerosis, and 49 Cases; leukemia intracranial infiltration of secondary bleeding in 3 cases; brain metastases with hemorrhage in 5 cases; coagulation disorders secondary to intracranial hemorrhage in 2 cases; unexplained bleeding in 7 cases. A total of 132 patients with a clear cause of bleeding were identified by MSCTA before treatment. The coincidence rate between MSCTA diagnosis and final pathology was 80.5%. Conclusion: MSCTA can be used as a screening method for intracranial spontaneous hemorrhage, which can provide an effective basis for imaging diagnosis of spontaneous intracranial hemorrhage.
