Synopsis

TGSE-BLADE DWI has been reported to reduce geometric distortion and susceptibility artifacts. However, it is unknown whether it reduces the clip-induced artifacts and improves image quality in patients after cerebral aneurysmal clipping. We compared the distortion and the artifacts between SS-EPI, RESOLVE, and TGSE-BLADE DWI in healthy volunteers and patients with a cerebral aneurysmal clip. TGSE-BLADE DWI has the best image quality regarding distortion and artifacts, especially at air-bone interfaces and near metal clips, which suggests that TGSE-BLADE DWI is a promising method for evaluating lesions at air-bone interfaces and scanning the patients with a clip.
