OBJECTIVE: To develop a non-invasive method for the detection and assessment of early-stage plaque.  Originally using a novel contrast agent particles that have specific ligands which target inflammation, a symptom of the presence of vulnerable plaque, the current technology uses an approved contrast agent and a clinical MRI system with known imaging sequences to generate a “vulnerability score”.  The current rabbit model allows for plaque rupture and confirmation of vulnerability score, with a strong correlation between rabbit aortae plaques and reported human plaque histology.
