At high field, MRI systems offer a higher signal-to-noise ratio, but B1+-inhomogeneity-induced artefacts in large organs can lead to shading and erroneous contrast. In this work, subject-tailored kT-points pulse design performance was evaluated in clinical routine on liver DCE-MRI at 3T, against that of patient-specific RF shimming. Both excitation homogeneity simulation and image quality assessment were performed on a variety of patients. The interest of kT-points is clearly demonstrated, as well as the reliability of the approach.
