Comparison between CT Angiography and Color Doppler Ultrasonography of Carotid Artery Stenosis

Abstract

Given the seriousness of carotid artery stenosis (CTA) and its being an important cause of ischemic strokes the resulting cases of disability and death around the world made it necessary to study the carotid arteries using various medical imaging methods accurately determine the degrees of stenosis and its location. Multi-Detector Computed Tomography Angiography (MDCTA) has played an important role in diagnosis, but it's a relatively invasive investigation due to the need to inject contrast material intravenously. This poses a problem in patients suffering from renal failure or sensitivity to the contrast material, cost also plays an important role due to patients' inability to bear these costs. Given the greater availability and wider scope of Color Doppler Ultrasound imaging on the one hand, and the ease of performing it, being a non-invasive and safe procedure, and relatively less expensive on the other hand, the need has emerged to study the role of CDUS and its importance in diagnosis, while investigating its accuracy and sensitivity. This study aimed to compare the degree of CAS determined by CDUS and that MDCTA.
