Diagram of T2prep sequence for the measurement of myocardial T
-weighted images. The sequence begins with a T2prep module followed by a N-line of gradient-echo data acquisition using a flip angle of β. All pulses in T2prep module are composite pulses. The acquisition continues until the full k-space lines are collected. The second TE2 images are then acquired in the same manner, followed by the TE3, TE4, etc.
