Absolute quantification of R1 and R2 relaxation and proton density PD has been gaining considerable attention in the recent years. As yet, simultaneous quantification of R1, R2 and PD has been restricted to 2D methods, with high resolution in-plane but using relatively thick slices. A previously published method on cardiac quantification, QALAS, has been applied to the brain, providing a full quantification of R1, R2 and PD at 1.2 mm isotropic resolution in 3D using only 6 minutes scan time.
