Defining carotid plaque characteristics predictive of stroke using non-invasive MR imaging is clinically relevant, but has been mostly limited to qualitative visualization of signal intensity in multi-contrast MR images. Here we present two robust and fast T2 and T1 mapping techniques based on radial data acquisition and demonstrate them in terms of carotid plaque characterization.
