An analysis of the effect of B1 inhomogeneity on spin density and T1 contrasted images is here given. Distortions both in saturation recovery and inversion recovery sequences are found. The impact of these distortions on in 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.

Abstract
An analysis of the effect of B1 inhomogeneity on spin density and T1 contrasted images is here given. Distortions both in saturation recovery and inversion recovery sequences are found. The impact of these distortions on in 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.File in questo prodotto:
