Mean and standard deviation of the T2 estimates on agarose gel phantoms are shown. The reference values were obtained from a single-echo spin-echo experiment as described in the Methods section. Note that the estimates from the proposed MB-DIR-RADFSE pulse sequence are closer to those from a single slice excitation scheme while the T2-prep bSSFP over-estimates the T2 values
