Purpose: To assess the diagnostic capability of 3.0T high-resolution arterial wall imaging (HR-MRI) in pts with suspected CAD. Methods: 11 patients underwent cervical MRI at 1.5 T (T1w-TSE, T2w-TSE, CE-MRA) and HR-MRI at 3.0T (Gyroscan Intera, Philips). HR-MRI was acquired using a phased array coil with four circular elements allowing for imaging of carotid and vertebral arteries. The HR-MRI-protocol consisted of: 1) bright blood 3D inflow MRA (TR/TE/FA=25 ms/3.1 ms/16°, 120 slices, reconstructed voxel size 0.3×0.3×0.8mm); 2) black blood cardiac gated water selective T1w 3D spoiled GE (TR/TE/FA=31 ms/7.7 ms/15°,…
