angiogram
Pronunciation: AN-jee-oh-gram
A radiographic image of blood vessels obtained after injection of contrast material to visualize vascular anatomy and pathology.
Full Definition
An angiogram is a diagnostic imaging study that provides detailed visualization of blood vessels throughout the body. The procedure involves injecting contrast material into the vascular system and taking X-ray images to reveal vessel structure, blockages, malformations, or other abnormalities. Angiograms are essential for diagnosing vascular diseases and planning interventional procedures. The term is often used interchangeably with arteriogram, though technically angiogram encompasses both arterial and venous imaging.
Usage
Usage note: Distinguish from angioplasty (a treatment procedure) when editing medical reports.
