Currently, we have developed tm-SPICE pulse sequences for the traditional (uni-axial, \(I_x \rightarrow S_x\)) magnetization transfer, and TROP pulse sequences performing transverse mixing (simultaneous \(I_x \rightarrow S_x\) and \(I_y \rightarrow S_y\)) that allow to systematically enhance sensitivity by \(\sqrt{2}\) for each indirect dimension.
