Abstract

Upper Extremity CT-Scan Angiography (CTA) Examination Procedure in Right Subclavian Artery Pseudoaneurysm Cases at Primaya Hospital Tangerang. Upper Extremity CT-Scan Angiography (CTA) is described as a technique for non-invasively evaluating vascular structures via peripheral contrast injection. Upper Extremity CTA is carried out starting from patient preparation, tools and materials used, examination protocols, and image reconstruction techniques. In addition, the contrast infusion technique must also be appropriate to provide an informative image.
