Left column: graphic representations of the pulse shapes. Center column: T2* values of a homogeneous phantom at different gradient strengths. Error bars indicate the SD of different T2* values measured in voxels experiencing the same gradient strength. Right column: SNR at different gradient strengths (TE = 48 ms). Row A, Exponentially shaped pulse. Row B, Sinc-shaped pulse. Row C, Sinc-Gauss–shaped pulse.

A, Susceptibility gradient map. Also shown are uncorrected (top) and corrected (bottom) T2* maps of a section of a homogeneous phantom with exponential (B), sinc (C), and sinc-Gauss (D) excitation pulses.
- Fig 3.
In vivo T2* maps of 2 sections. From left to right: smoothed through-plane gradient map; uncorrected T2* map acquired with an exponential pulse; corrected maps with exponential, sinc, and sinc-Gauss pulses.
