Figure 1

Tagging by magnetization saturation. The technique is based on implementing slice-selective magnetization saturated planes orthogonal to the imaging slice. (a) Pulse sequence. Each tagging plane needs a slice-selective RF pulse during the tagging stage. The imaging part follows tagging, and the figure shows conventional Cartesian acquisition (RO = readout, PE = phase encoding, SS = slice selection). (b) Tagging planes and imaging slice.
