A simple method for the restoration of signal polarity in multi-image inversion recovery sequences for measuring T1.
A simple scheme for the polarity correction of absolute images from inversion recovery multi-image T1 measurement sequences is described and demonstrated. This method is less sensitive to errors from eddy currents than the conventional full phase correction schemes and does not involve an increase in measurement time as it requires no additional scans.
