Giant-cell arteritis is the most common vasculitis. MRI is a powerful tool for the depiction of the inflamed cranial arteries, but in a clinical setting this requires sub-mm resolution and fast measurement times. We evaluated the performance of two high-end receive array coils for the imaging of superficial temporal and occipital arteries wall in healthy volunteers on a 3T clinical scanner. The results show clearly improved imaging performance is achieved with the more focused coverage of an experimental 95-channel head coil compared to the commercially available high-end head coil.
