Synopsis

In this work, we demonstrate a parallel transmit implementation of velocity selective arterial spin labelling (VSASL) at 7 Tesla on a custom flow phantom developed in house. The use of tailored pTx pulses can greatly mitigate the transmit field inhomogeneities present at higher field strengths. By manipulating the time symmetry of the pTx pulses in the VSASL module we were able to show significant improvement in velocity selective inversion fidelity.
