Original Abstract

The paper presents the assessment and correction of B1 induced errors in magnetization transfer ratio measurements, where new method is presented for fast and accurate large volumetric radio frequency (RF) field. This method is a modiffication of the Double Angle Method (DAM), which accelerates imaging speed and applies 3D imaging. The aims of this Paper are to describe B1 errors in Magnetization Transfer Ratio (MTR) and to reduce MTR histogram dispersion using B1 field mapping. The proposed B1 field mapping sequence for the study is the DAM. In order to reduce acquisition time, an FSE sequence was used in this study. The FSE sequence was performed twice, with the excitation stage of the sequence altered.
