| Popis: | There is limited evidence of parametric MR mapping to characterize carotid plaques associated with cerebral ischemic events.To explore the apparent diffusion coefficients (ADCs) and longitudinal relaxation rates (RTwelve patients who underwent carotid endarterectomy.RA phantom study using diluted gadolinium solutions and polyvinyl alcohol solutions was used to validate the two protocols. Regions of interest (ROIs) were manually outlined on MR images for areas of LR/NC, hemorrhage, and Fbr based on histological cross-sections. Pixel-based RThe RRThe combination of ADC and R1 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018;48:1657-1667. |
