Traditionally, T2 weighting in MR is controlled by varying the sequence echo time (TE). Alternatively, T2 contrast can be generated from the RF pulse itself. Using theoretical calculations and Bloch simulations we study ways to maximize T2 weighting generated by this mechanism. It is shown that the pulse duration is the primary means to adjust the peak of the T2 weighting function toward the tissues of interest.
