We demonstrated the feasibility of two novel 3D imaging techniques for the purpose of quantitative T1 as well as multi-component T2-relaxation measurements under clinical relevant time constrains (<25min) at high magnetic field strength (3T). T1 measurements were performed by means of a 3D inversion prepared ultra-fast gradient echo sequence with radial encoding and elliptical k-space shutter. A 3D 32-echo CPMG sequence with slab selective refocusing pulses were used for multi-component T2 measurements.
