Though T2 mapping is desirable in many clinical applications it is not preferred due to the long acquisition times associated with the conventional Spin Echo (SE) sequence. Turbo or fast SE sequences though considerably faster than spin echo are not suitable for T2 mapping due to the stimulated echoes associated with them. Here we present an alternative technique based on DESS (Double echo steady state) to produce T2 maps.
