TGSE-BLADE DWI has been reported to reduce geometric distortion and susceptibility artifacts, however the long acquisition time prevent its clinical application. We reduced acquisition time to 1 minute for TGSE-BLADE DWI using slice acceleration (1-min TGSE-BLADE DWI). We compared distortion and artifacts between SS-EPI DWI and 1-min TGSE-BLADE DWI, and evaluated diagnostic performance for acute infarctions of 1-min TGSE-BLADE DWI. The result shows that the 1-min TGSE-BLADE-DWI has better quality image in terms of distortion and artifacts, and higher diagnostic performance for acute infarctions. TGSE-BLADE DWI with slices acceleration is a promising method for evaluating lesions in acute stroke patients.
