Cineangiography

Part of speech: noun

Definitions

1. A medical imaging technique that utilizes contrast agents and X-rays to visualize the patency and structure of blood vessels
2. A diagnostic process that captures images of blood vessels using injected contrast material and X-ray technology
3. A method in medicine where blood vessels are made visible by introducing a dye and then photographing them with X-rays

Etymology: Cineangiography is a compound built from two medical terms joined together. Its second half, "angiography," describes the imaging of blood vessels using a contrast agent injected into the bloodstream, which makes the vessels show up on X-ray images. The first half, "cine-," comes from the Greek "kinema," meaning movement, and in medicine it signals that a series of images is recorded in rapid succession rather than a single still picture. Put together, the term describes angiography that is filmed as a moving sequence. This lets physicians watch blood flowing through the vessels in real time, judging whether they are open, narrowed, or blocked, and how the contrast agent travels through them. A single still image can miss what a continuous recording reveals about flow and timing.
