The Rapid Relaxometry through Acquisition of Multiple Saturated T2 Curves (RRAMSC) technique is, in theory, limited to STEAM localization, where the recovery period allows specific control of the degree of longitudinal magnetization that recovers. Because PRESS lacks a well-defined recovery period, RRAMSC trade-off between changes in the TE and TR, to keep saturation effects constant, cannot be calculated over a generic range of different T1 values. Here we examine the effects of approximating the recovery when employing RRAMSC with PRESS localization.
