Imaging the carotid arteries at 7T requires a multichannel array which allows B1-shimming and conforms to different neck sizes. The major challenge is to minimise coupling between closely-spaced coils and to make the coupling relatively insensitive to loading conditions. We have designed a five channel transceive array composed of shielded-coaxial-cable coils placed on the anterior part of the neck and conforming to the anatomy. Coil flexibility has been demonstrated by imaging subjects with different neck circumferences. In vivo black-blood images were acquired with very high in-plane spatial resolution (0.25 x 0.25 mm2) with clear depiction of the vessel walls.
