3D-FSE-XETA-T1WI平扫序列在评估MCA狭窄中的诊断价值:VWI多序列与DSA的对照研究
The Diagnostic Value of 3D-FSE-XETA-T1WI Plain Scan Sequence in Evaluating MCA Stenosis:A Control Study of VWI Multi-Sequence and DSA
摘要
Abstract
Objective To explore the differences in evaluating the stenosis rate of the middle cerebral artery(MCA)by comparing multi-sequence of magnetic resonance vessel wall imaging(VWI)with DSA,and to clarify the diagnostic value of the optimal sequence. Methods A retrospective collection of imaging and clinical data was conducted on patients who visited the First Hospital of Qinhuangdao from March 1,2022,to August 31,2023,who were confirmed to have stenosis or occlusion of the MCA-M1 segment by VWI and DSA examinations.The intra-class correlation coefficient(ICC)was used to evaluate the consistency in measuring the luminal stenosis rates of the MCA-M1 segment between five VWl sequences[3D fast spin echo with an extended echo train acquisition(3D-FSE-XETA)-T1WI plain scan+enhancemend,2D-T2WI,2D-T1WI plain scan+enhancemend]and DSA.ROC curves were plotted to compare the diagnostic efficacy of the five sequences for severe stenosis and occlusion. Results A total of 70 patients were included,with an average age of(58.16±10.68)years,among whom 43 were male(61.4％).The overall consistency of the MCA-M1 segment stenosis rates measured by the five sequences of VWI and DSA was excellent[ICC 0.96(0.94-0.97),P＜0.001].Among these sequences,the 3D-FSE-XETA-T1WI plain scan sequence had the best consistency[ICC 0.88(0.81-0.93),P＜0.001],and its diagnostic efficacy for severe stenosis and occlusion was superior to that of the 2D sequences[AUC 0.78(0.67-0.87),P＜0.005]and comparable to that of the 3D enhanced sequences(P=0.143). Conclusions The 3D-FSE-XETA-T1WI plain scan sequence in VWI is superior to other sequences in evaluating the stenosis rate of the MCA-M1 segment and can serve as an effective method to assist DSA in evaluating the stenosis severity before clinical surgery.关键词
