Figure 1

Spin magnetization (top) and sequence diagram (bottom). The sequence diagram (bottom) shows Time-SLIP with two-dimensional cine bSSFP. The corresponding magnetization states (top) of signals covered by the non-selective pulse (A) and the selective tagged pulse (B) are presented. An initial non-selective pulse (A) inverts all magnetizations within a radiofrequency coil, followed by a selective pulse (B) that restores the magnetization at + Mz in a plane that can be placed freely in any orientation. The untagged background signals, receiving only the non-selective inversion recovery (IR) pulse return to + Mz by following T1 recovery relaxation, as shown in the dotted line. After waiting, a TI, cine bSSFP read-out is acquired. When the untagged signals reach a null point, the tagged signals and the untagged signals have maximum contrast and thus they are well differentiated.
