Quantitative contrast ratio comparison between T1 (TSE at 1.5T FLAIR at 3T) magnetization prepared rapid gradient echo and subtraction imaging at 1.5T and 3T

摘要

IntroductionCreating contrast between normal anatomy and pathology is the main goal of imaging. Here we compare contrast ratios of enhancing brain lesions at 1.5T between T1 TSE, magnetization prepared rapid gradient echo (MPRAGE) and subtraction and at 3T between T1 FLAIR, MPRAGE and subtraction.
