A subtractive time of flight technique for MR angiography and quantitative blood flow measurement. Proton spins of water in the arterial supply to a tissue or organ are inverted in a steady-state fashion by applying constant amplitude off-resonance radio frequency pulses in the presence of a constant...http://www.google.fr/patents/US5320099?utm_source=gb-gplus-shareBrevet US5320099 - MR angiography using steady-state transport-induced adiabatic fast passage
