It is demonstrated that the location of the auto calibration lines for parallel imaging schemes should be selected carefully, when the k-space lines are acquired with different signal weighting. To illustrate this point, we study the effects of auto-calibrated parallel imaging in fast spin-echo data and propose a view ordering scheme that minimizes the artifacts due to the differences in signal weighting caused by T2 decay.
