Intima–media thickness (IMT), also called intimal medial thickness, is a measurement of the thickness of tunica intima and tunica media, the innermost two layers of the wall of an artery. The measurement is usually made by external ultrasound and occasionally by internal, invasive ultrasound catheters .
The tunica intima (Neo-Latin "inner coat"), or intima for short, is the innermost tunica (layer) of an artery or vein. It is made up of one layer of endothelial cells (and macrophages in areas of disturbed blood flow), [ 1 ] [ 2 ] and is supported by an internal elastic lamina .
The healthy epicardial coronary artery consists of three layers, the tunica intima, media, and adventitia. [ 10 ] [ 11 ] Atheroma and changes in the artery wall usually result in small aneurysms (enlargements) just large enough to compensate for the extra wall thickness with no change in the lumen diameter.
The tunica media is made up of smooth muscle cells, elastic tissue and collagen.It lies between the tunica intima on the inside and the tunica externa on the outside.. The middle coat (tunica media) is distinguished from the inner (tunica intima) by its color and by the transverse arrangement of its fibers.
The intima-media thickness of the carotid artery wall is a marker of subclinical atherosclerosis and it increases with age and with long-term exposure to particulate ...
Testing for plaque includes a carotid intima-media thickness test, (CIMT), which measures blood flow through the arteries and the thickness of the arteries. [2] [3] Physician Dr. Jeff Emery wrote that the test "allows us to identify if you are at future risk for a heart attack or stroke."

Intima-media thickness, which is positively correlated with reduced blood flow, was studied in young smokers. Evidence pointed towards smoking as a major risk factor for increased levels of PLA2, due to tobacco smoke's impact on oxidation of retained LDL particles in the intima of a carotid artery, [ 17 ] which may have a detrimental impact on ...
