arteriogram
An imaging study that visualizes arteries using contrast material, typically obtained through catheter-based angiography.
Full Definition
An arteriogram is a diagnostic imaging study that provides detailed visualization of arterial structures through the introduction of contrast material directly into the arterial system. This procedure typically involves catheter-based techniques where a catheter is inserted into an artery and contrast is injected while X-ray images are obtained. Arteriograms offer superior resolution and dynamic information compared to non-invasive imaging methods, making them the gold standard for evaluating complex vascular pathology. The procedure allows for both diagnostic assessment and therapeutic intervention during the same session.
Usage
Usage note: Specifically refers to arterial imaging; use 'angiogram' for general vascular imaging.
