摘要
目的 探讨彩色多期CT血管成像(ColorViz mCTA)对大、中动脉闭塞性脑梗死的诊断价值.方法 选取本院急性缺血性脑卒中患者 306 例,均完成多期CTA及MRI-DWI检查.多期CTA血管信息由FastStroke软件汇总.对比ColorViz mCTA对于大、小梗死灶的检出差异性,分析ColorViz mCTA与区别大、小病灶之间的相关性,利用ROC曲线评价ColorViz mCTA对区分大、小急性脑梗塞灶的诊断价值.结果 共检出 323 个病灶,其中大、中动脉闭塞性梗死灶共190 个,小动脉闭塞性脑梗死灶 133 个.病灶越大,ColorViz mCTA检出率越高(P<0.001),并且ColorViz mCTA与病灶大小有显著相关性(r=0.749,P<0.001);ColorViz mCTA区分大、小病灶曲线下面积(AUC)为 0.933(P<0.001),当病灶面积等于 2.53 cm2 时,ColorViz mCTA具有最大诊断效能,敏感度为 91.1%,特异度为 86.1%.结论 利用ColorViz mCTA可对脑大、中动脉闭塞性脑梗死针对性诊断.
Abstract
Objective To explore the diagnostic value of ColorViz multi phase CT angiography(ColorViz mCTA)in large and middle artery occlusion cerebral infarction.Methods A total of 306 patients with acute ischemic stroke in our hospital were selected.All patients were completed multi-phase CTA and MRI-DWI examination.Multi stage CTA vascular information was summarized by FastStroke software.Then,we compared the differential detection of ColorViz mCTA for large and small in-farcts,analyzed the correlation between ColorViz mCTA and distinguishing large and small infarcts,and evaluated the diagnos-tic value of ColorViz mCTA for distinguishing the large and small acute cerebral infarction using receiver operating characteristic curve(ROC).Results A total of 323 lesions were detected,there were 190 cases of large and middle artery occlusive infarc-tion and 133 cases of small artery occlusive cerebral infarction.The larger the lesion,the higher the detection rate of ColorViz mCTA(P<0.001),and there was a significant correlation between ColorViz mCTA and lesion size(r=0.749,P<0.001);Color-Viz mCTA could distinguish the large and small lesions with an area under the curve(AUC)of 0.933(P<0.001).When the le-sion area was equal to 2.53 cm2,ColorViz mCTA had the maximum diagnostic efficacy,with a sensitivity of 91.1%and a specific-ity of 86.1%.Conclusion ColorViz mCTA can be used for the targeted diagnosis of large and medium cerebral infarcts caused by cerebral artery occlusion.
