摘要
目的:探讨64层容积CT数字减影血管造影(Volume computed tomography digital subtraction angiography,VCTDSA)联合CT灌注成像在急性缺血性卒中诊断价值。方法:回顾性分析45例临床确诊为急性缺血性卒中患者的临床资料,分别给予VCTDSA与CT灌注成像处理,分析这两种技术对急性缺血性卒中患者的诊断敏感性和特异性。结果:45例患者检查有颅内有不同部位出血灶,多见于脑室,均伴有不同程度的异常血管网形成,其中VCTDSA图像质量优于CT灌注成像,VCTDSA较DSA可准确显示和测量动静脉瘘口大小,VCTDSA与MRA在瘤体长轴、瘤颈的比较中无显著性差异。结论:与其他减影CTA比较,VCTDSA联合CT灌注成像在急性缺血性卒中患者的诊断中具有优势。
Objective： To explore the 64-slice volume CT digital subtraction angiography （the Volume computed tomography digital subtraction angiography, VCTDSA） combined with CT perfusion imaging in the diagnosis of acute ischemic stroke value. Methods： Retrospective analysis of 45 patients with clinically diagnosed as clinical data of patients with acute ischemic stroke, respectively to give VCTDSA and CT perfusion imaging processing, and analysis of diagnostic sensitivity and specificity of these two technologies in patien- ts with acute ischemic stroke. Results：45 patients check intracranial bleeding lesions in different parts, more common in the ventricles, are associated with varying degrees of abnormal vascular network formation, which VCTDSA image quality is superior to CT perfusion imaging, VCTDSA than DSA can accurately display and measurement of arteriovenous fistulathe size, VCTDSA, and MRA was no significant difference in tumor long axis, the comparison of the aneurysm neck. Conclusions： The other subtraction CTA VCTDSA combined with CT perfusion imaging in the diagnosis of acute ischemic stroke patients have an advantage.
