Contains numerous figures, tables SE Sequences. This chapter describes several pulse sequences commonly used in Explains pulse sequences, their components, and the associated image reconstruction methods commonly used in MRI. Provides self-contained sections for individual techniques. As the spinning nuclei go through T1, T2, and T2* relaxation, the transverse magnetization is gradu ally dephased. P Scan time = TR x N x NSA. Options include spoiled GE, steady-state GE. Does not rephase effects of B0 inhomogeneity, chemical shift, or magnetic susceptibility Abstract. Produces T1 or T2* contrast. In SE sequences, a° pulse flips the net magne tization vector into the transverse plane (10). This allows very short TR. Uses gradients to rephase echo. Can be used as a quick reference guide or as a resource for deeper study. Includes both non-mathematical and mathematical descriptions.
