The magnetization transfer effect of the QRAPMASTER sequence was investigated using phantom experiments and Bloch simulations. The phantom consisted of MnCl2 aqueous solution with various proton T1 values and raw chicken breast meat. T1 values of the MnCl2 solution measured using the QRAPMASTER sequence showed excellent linear relation with those measured with the standard method. However, T1 of the chicken breast sample deviated far from the linear regression line. The results suggested that the T1 values of biological samples measured by the QRAPMASTER sequence are underestimated compared to those measured by the standard method.
