Claim 0:
1. A method of assessing the level of vascular inflammation in a patient in need thereof, the method comprising:
determining a perivascular water index (PVWi) of a blood vessel by:
(i) using data gathered from a computer tomography scan along a length of the vessel to determine a total volume of voxels of water within an attenuation window around the attenuation of water within a perivascular space a pre-determined distance from an outer wall of the vessel, and
(ii) correcting the total volume of the voxels of water for the volume of the vessel by dividing the total volume of voxels of water determined in step (i) by the total perivascular volume; and

determining the level of vascular inflammation in the patient using the perivascular water index.
