It has been shown recently that quantitative T-2-maps may be measured
by acquisition of a series of at least eight T-2-weighted SNAPSHOT FLA
SH images. These measurements require a relaxation delay of 10-15 s af
ter each T-2-weighted image for the complete relaxation of the spin sy
stem. This results in long measuring times. The method presented in th
is paper allows a considerable reduction of the measuring time by comb
ining the T-2-sequence with a fast T-1-measurement. Quantitative T-1-
and T-2-maps may be acquired simultaneously in less than 30 s. The met
hod was tested in a phantom experiment. In an in vivo application, rel
axation times of different tissues in the abdomen of a rat were measur
ed.
