Limitations and potentials of adiabatic TSE for human application at 7T have been demonstrated. The limitations of the adiabatic regime, when going to lower B₁ fields, are discussed and the importance of correct k-space sampling has been shown. Furthermore, compared to a conventional TSE, an adiabatic TSE improves the homogeneity of the image. This is simulated and confirmed in phantom measurements as well as in vivo, on the primary visual cortex and the left carotid artery, using a transmit and receive surface coil.
