• The aim of this study was to evaluate the measurement precision and accuracy of T mapping using a polarity corrected (PC) TI prep tool, which was based on fast field echo (FFE) and obtained one data point with one inversion recovery (IR) pulse. A phantom was used consisting of eight materials with different Gd concentrations. T mappings were measured by changing the trigger interval and the inversion time (TI) interval. The T mapping measurement precision using the PC TI prep tool increased as the trigger interval was made longer. The measurement precision didn't depend on the interval of TI. On the other hand, when the trigger intervals are more than 1000 ms, the measurement accuracy was less than approximately 8%. By setting the optimal end of TI, the T mapping using a PC TI prep tool could measure the T value precisely and accurately.
