IR-TrueFISP was recently introduced for quantification of tissue relaxation times. With IR-TrueFISP only a single acquisition is needed to calculate T1-, T2-, PD- maps and synthetic images with various contrasts such as FLAIR. In this study, we compared IR-TrueFISP with conventional methods to measure brain relaxation times in 5 pediatric patients. Data acquisition was 6 times faster with IR-TrueFISP, and there was excellent correlation between respective T1 and T2 maps (p<0.001).
