APOE and atherosclerosis: Using MR steady-state gradient echo sequence (GRE) developed specifically for molecular imaging of atherosclerosis, this strategy was utilised to (i) identify and characterise vulnerable plaques and (ii) quantitatively track inflammatory status of plaque progression, in the carotid arteries of an apolipoprotein E-deficient (ApoE−/−) cuff-implanted mouse model [7, 8, 10].
