An Exploration of the Value of diffusion-weighted imaging(b=0)for Cerebral Microbleeds
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.
