We developed interchangeable carotid coils that can image simultaneously with clinical head coils. Both 7 and 9 channel carotid coils were built to demonstrate the interchangeability concept. SNR results show that the 7 channel coil has ~4x the SNR and the 9 channel coil has ~3x the SNR of the commercial neck coil at the carotids. The carotid coils image simultaneously with a head coil providing greater coil sensitivity at the carotid bifurcation and extending total coverage from the carotid bifurcation to the circle of Willis.
