  • Carotid MR Imaging +

    Carotid MR Imaging Exploring the characteristics of vulnerable plaque is pivitol to the understanding of atherosclerosis disease progression. Traditionally, this has been done through histology, allowing for risk categories to be created. Dr. Moody et al., are using MR imaging (and PET imaging through CAIN2) to investigate tissue character, which, when related to histology, may be used to predict future events. It is anticipated that this knowledge could then be used for screening, for future long term trials, and to predict disease progression in the brain.
