While optimized Vessel Encoded Pseudo-Continuous ASL (opt-VEPCASL) provides higher SNR efficiency, randomly-encoded VEPCASL (re-VEPCASL) may provide other benefits such as: 1) no planning or angiogram is needed; and 2) it is potentially insensitive to resonance offsets. These advantages may benefit clinical users. In this abstract, the advantages of opt-VEPCASL and re-VEPCASL are discussed, and the efficiency of random encoding is examined by simulation.
