| Abstract: | Summary An analysis of the effect ofB
1 inhomogeneity on spin density andT
1 contrasted images is here given. Distortions both in saturation recovery and inversion recovery sequences are found. The
impact of these distortions onin vivo spectroscopy, where quantitative data are required, is also discussed. In general, these aspects are found to be reduced
at shortertime parameters of the pulse sequences.
