Objective To explore the feasibility of three-dimensional (3D) vessel wall imaging of carotid atherosclerotic plaques in ApoE^-/- mice using 7.0T magnetic resonance imaging (MRI) with delays alternating with nutations for tailored excitation (DANTE)-prepared fast low-angle shot (DANTE-FLASH) technique. Methods Numerical simulations were performed for optimizing imaging parameters to maximize the wall-lumen contrast. Six ApoE^-/- and three wild-type mice were scanned using a 7.0T MRI scanner with DANTE-FLASH and multi-slice 2D RARE coupled with inflow outflow saturation bands (2D-IOSB-RARE). The wall signal- to-noise ratio (SNRwall), lumen SNR (SNRlumen), wall-lumen contrast- to-noise ratio (CNR), lumen area (LA), and wall area (WA) were compared between DANTE- FLASH and 2D-IOSB-RARE sequences. Linear regression analysis was performed to assess the correlation between the MRI measurements and histopathological measurements of LA and WA. Results Based on the simulation results, a flip angle of 15° and a train length of 150 were implemented in the live imaging study. Compared with 2D-IOSB-RARE, DANTE-FLASH provided a slightly reduced CNR (P<0.001) but much improved slice resolution. The LA and WA measurements from the DANTE- FLASH and 2D- IOSB- RARE showed excellent agreement based on ICC analysis (LA: ICC=0.94, P<0.001; WA: ICC=0.93, P<0.001) and Bland-Altman plots. Strong correlations were observed between the MRI and histopathological measurements for both LA (P<0.0001) and WA (P<0.0001). Conclusion As a 3D black-blood MR sequence, DANTE-FLASH provides isotropic high spatial resolution to allow reliable visualization and quantitative evaluation of the arteriosclerotic lesions within the carotid artery of ApoE^-/- mice using a 7.0T MRI scanner.
