Carotid artery stenosis a physician detects a carotid bruit, or murmur, over the carotid artery by listening through a stethoscope during a physical exam. For people with symptoms, the American Heart Association recommends initial screening using ultrasound (see diagnosis below). Carotid artery stenosis is usually diagnosed by color flow duplex ultrasound scan of the carotid arteries in the neck. This involves no radiation, no needles and no contrast agents that may cause allergic reactions. This test has good sensitivity and specificity. Typically duplex ultrasound scan is the only investigation required for decision making in carotid stenosis as it is widely available and rapidly
Trabecular arteries elements of the pulp, and no doubt undergoes important changes. Trabecular arteries The trabecular arteries are the name of the branches of the splenic artery after it passes into the trabeculae of the spleen, where it branches. When these arteries then reach the white pulp, and become covered with periarteriolar lymphoid sheaths, the name changes again to "central arteries" (or "central arterioles"). Branches of the central arteries are given to the red pulp, and these are called "penicillar arteries"). The lienal artery is remarkable for its large size in proportion to the size of the organ, and also for its
