Nowadays, with the increase in the elderly population various vascular diseases are becoming more of a problem. Cerebral hemorrhage, stenosis and cerebral blocking resulted from thrombus formation in either the cardiac, or carotid artery are a number of examples which can cause cerebral infarction. In this study, carotid ultrasonography of patients with stenosis detected in both Margnetic Resonance Angiography (MRA) images and Duplex. ultrasound images are compared and analyzed by the degree of stenosis to acquire an accurate evaluation. Between October 2nd 2011, and June 2nd 2012, an investigation took place in St. Mary`s Hospital Seoul. 819 people (819 people x 2 vessels from 1638) were subject to the investigation. The investigation focused mainly on the entire carotid artery disease in patients. The investigation was carried out with the assistance of images of the Internal Carotid Artery (ICA), Duplex Ultrasound, and MRA of the Picture Archiving Communication System (PACS). Using the Gold standard as a guideline, MRA images can b classified as mild, moderate or severe depending on the degree of stenosis present in the 1CA. MRA images display higher results over ``oderate`` standard when it`` compared with ultrasound images. Unlike the Ultrasound images the Doppler image and the MRA image share some similarites. Some errors may be present when using ultrasound or MRA but by adding the doppler ultrasound study, evaluating the degrees of stenosis in the carotid artery will increase diagnostic accuracy.
