It's all radiofrequency, all the time. This educational e-poster explores some of the similarities between conventional continuous wave spin lock and balanced steady-state free precession sequence. By comparing the transient and steady-states of the two techniques, further insight is gained into the physical origins of the endogenous contrast generated by RF pulses.
