Calculation of tissue TI in double spin-echo imaging (90"-T-I 80"-2T-1 SO0) using two repetition times (6, and b2) has entailed an approximation that ignores the two 180" pulses. The theoretical consequence of the simplification is to overestimate TI with a fractional error that increases with incre
