In this work a method for considerably improving the signal-to-noise ratio (SNR) in T(1) maps based on the variable flip angle approach is proposed, employing spoiled fast low angle shot (FLASH) echo-planar imaging (EPI) hybrid sequences with two echoes per excitation. In phantom measurements it could be verified that the SNR improvement in the underlying images translated into an SNR increase in the T(1) maps exceeding theoretical predictions. Even a hybrid sequence with an 18% shorter… CONTINUE READING
