The adiabatic T and RAFF measurements, RAFF2 and RAFF4, were performed in 28 healthy volunteers (24-69 years) and four of them had repeated MR scan within 4 weeks to evaluate short term repeatability. The relative differences on the voxel level were below 5% in gray and white matter for all of the relaxation parameters except of TRAFF4 in gray matter which was 7.3%. No statistically significant age related changes in white and gray matter were present as evaluated by adiabatic T, RAFF2 and RAFF4 imaging.
