✦ Synopsis

The transverse relaxation effects which occur during the application of optimized slice-selective Shinnar-Le Roux pulses are studied. The behavior of both longitudinal and transverse magnetization is examined, focusing the attention on changes which affect the absorption and dispersion components. Besides the reduction in amplitude, the absorption component was found to be unaffected by transverse relaxation times, whereas the dispersion component was strongly distorted. A comparison between the distortion components from pulses having same length but different bandwidths is given.
