The RF coil could contribute significantly to the quality of the intracranial microvascular imaging in ultra-high-field MRI. We have investigated several different types of RF coils and analyzed their relative performance in terms of SNR profiles and resolutions. The overlapped 6-channel coil exhibited highest performance, especially for angiographic imaging, due to its improved penetration depth, i.e., overall improved SNR.
