Document Summary

Enabling penetration of solid materials of varying densities. Visualizes internal organs/structures, providing verification of presence of illness or disease. Procedures and techniques of radiology and diagnostic imaging. Specialized diagnostic procedure in which a catheter is introduced into a large vein or artery. Usually of an arm or a leg. Catheter is then threaded through the circulatory system to the heart. Series of x-ray films allowing visualization of internal structures after the introduction of a radiopaque substance. Injection of a radiopaque contrast medium into an arterial blood vessel (carotid, femoral, or brachial) making possible the visualization of the cerebral vascular system via x-ray. X-ray visualization of the internal anatomy of the renal blood vessels after the injection of a contrast medium. X-ray visualization of arteries following the introduction of a radiopaque contrast medium into the bloodstream through a specific vessel by way of a catheter. Process of taking x-rays of the inside of a joint.
