The utility of a custom gradient coil insert for scanning carotid plaques was assessed. The gradient coil insert works in conjunction with the whole body gradient system of a clinical scanner to increase overall gradient performance. Excised carotid plaques were imaged on a 3T clinical scanner with and without the gradient coil insert and images were compared. Plaque images obtained using the dual gradient mode had twice the spatial in-plane resolution of those obtained without it. This novel gradient system may be used to improve clinical carotid MR studies by increasing the resolution of in-vivo plaque images.
