T2-weighted contrasts in rapid low flip-angle imaging.
Expressions for the contrast-to-noise (C/N) behavior in images obtained from rapid low flip-angle excitation pulses are derived, taking into account both T1- and T2-dependent contrasts. It is shown, and demonstrated experimentally, that images with T2-weighted contrasts can be efficiently acquired with such sequences, by a suitable choice of TR, TE, and tip angle.
