[The Effect of Scan Parameters on the Synthetic MRI].

Synthetic MRI can provide proton density (PD), T value, T value for each pixel by only one data acquisition and can create various contrast-weighted images. The aim of this study is to evaluate the effect on the calculation of the T·T value when changing the scan parameters for synthetic MRI. In the phantom study, when changing 1st TE/2nd TE/TR/TSE factor, the effect on the T·T value calculated by synthetic MRI was examined. In the volunteer study, the brain was imaged and compared with known T·T value. In phantom study, the effect on the T value by the 1st TE/2nd TE/TSE factor was shown. In volunteer study, there was no problem in the calculated value of brain parenchyma. However, the T value of cerebrospinal fluid had the error of known value. The results show that it is necessary to set appropriate scan parameters on synthetic MRI.
