摘要
目的:探讨弥散加权成像(Diffusion-weighted imaging,DWI)(b=0)对脑微出血的检查价值,为临床发现和检出脑微出血提供早筛、省时的方法.方法:选取2022年3月至2023年3月上海市某医院收治的51例确诊脑微出血患者,分别行T2FLAIR、DWI及SWAN三个序列检查;记录每例患者幕上和幕下脑微出血灶的检出数,分别统计T2FLAIR、DWI(b=0)与SWAN检出一致性.结果DWI(b=0)在幕上和幕下脑微出血灶检出数上明显多于T2FLAIR检出数(p<0.05);DWI(b=0)与SWAN组内相关系数一致性高ICC=0.828(95%CI0.674～0.913).结论:DWI(b=0)一定程度可以替代SWAN检查,在可疑脑内小血管病时可作为早筛、诊断CMBs的方法.
Abstract
Objective:To investigate the value of diffusion-weighted imaging(DWI,b=0)for the detection of cerebral mi-crobleeds,and to provide an early screening and time-saving method for clinical detection and diagnosis of cerebral microbleeds.Methods:Fifty-one patients with confirmed cerebral microbleeds admitted to a hospital in Shanghai from March 2022 to March 2023 were selected to undergo T2 FLAIR,DWI,and SWAN examinations.The number of supra-and subcortical cerebral micro-bleeds detected by the above sequences was recorded for each patient,and the agreement between T2 FLAIR and DWI(b=0)was assessed separately with SWAN detection.Results:The intragroup correlation coefficient between DWI(b=0)and SWAN was ICC=0.828(95%CI 0.674-0.913).Conclusion:DWI(b=0)can replace SWAN examination to some extent in detecting ce-rebral microbleeds and can be used as a method for early screening and diagnosis of cerebral microbleeds in suspected small ves-sel disease.Early screening and diagnosis of cerebral microbleeds is essential.
