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.
