intima-media thickness

,

IMT

The depth in millimeters of the two inner layers of an arterial wall. IMT is a marker of generalized atherosclerosis. It increases with age, cholesterol intake, smoking, body mass index, and other established risk factors for cardiovascular disease. IMT is measured ultrasonographically, typically in the carotid arteries.
