Abstract

The hyperbolic secant inversion pulse has been incorporated into the interleaved saturation-recovery/inversion-recovery sequence to provide T1 measurements combining high precision with a significantly reduced imaging time (a mean accuracy of 2% over a T1 range of 300 to 1650 ms for standard gel phantoms, with Tr1 = Tr2 = 2.0 s, Ti = 0.67 s).
