In vivo evaluation of the proposed fast radio-frequency enforced steady state spin echo (FRESS-SE) MRI. (a) T2 maps of a rat brain with chronic stroke (~24 h after onset of permanent MCAO) using conventional SE sequence with TR = 6 s (left) and TR = 1.6 s (second from left), and using the proposed FRESS SE sequence with TR = 1.6 s (third from left). All T2 maps (in ms) are displayed at the same scale. (b) T2 histogram of two regions of interest, one from ipsilateral ischemia area and another from the contralateral normal region. (c) T2 difference (proposed sequence – conventional sequence) map (in ms) is computed for TR = 1.6 s (bottom row).
