Fast 3D T2 Measurement with a Magnetization Prepared TrueFISP Sequence

Philipp Krmer¹, Lothar R. Schad¹

3D spin-echo and turbo-spin-echo T₂ weighted imaging suffers from high acquisition duration because of the necessary long repetition times. For 2D cardiac T₂ measurement a sequence was proposed which applies two 90 rectangular pulses and a Malcolm-Levitt composite pulse train of four 180 refocusing pulses for T₂ weightening prior to imaging. In this work, the same T₂ preparation method is combined with a fast 3D TrueFISP imaging sequence enabling fast 3D T₂ measurement.
