On 7 Tesla we measured the relaxation times T1 and T2 of the human calf with separate consideration of muscle tissue and subcutaneous fat tissue. A saturation recovery and spin echo sequence with non-equidistantly adapted TI and TE (that match to T1 and T2 respectively) was used to get a linear sampling on the magnitude axis. For comparison with lower field strength, all measurements were also carried out on a 3T scanner and are compared with literature.
