What does arteriogram mean?
An arteriogram is an X-ray image of an artery or arteries, rendered visible through the injection of a radiopaque contrast dye that outlines the vessel on film or a digital display. The word can also denote the imaging procedure itself, though the technique is more formally called arteriography. Arteriograms are central to diagnosing vascular disease: they reveal blockages, narrowing, aneurysms, and malformations in arteries supplying the heart, brain, kidneys, and limbs. A coronary arteriogram, for example, remains a key step in evaluating patients suspected of having blocked heart arteries. Strictly speaking, an arteriogram depicts arteries only; the broader term angiogram covers any blood vessel, including veins. Because the word derives from Greek roots meaning 'artery' and 'written record', it belongs to a large family of medical imaging terms ending in '-gram', such as cardiogram and encephalogram. It is a formal, technical term encountered mainly in hospitals, radiology reports, and medical literature.
nounAn X-ray image of an artery or arteries, made visible by injecting a radiopaque contrast dye into the bloodstream. The term also refers to the procedure of producing such an image.
- An X-ray image of one or more arteries made visible by injection of a radiopaque contrast medium.
- The medical procedure or technique of producing such an image (more commonly termed arteriography).
"The cardiologist ordered a coronary arteriogram to pinpoint the blockage causing the patient's chest pain."
"The radiologist reviewed the femoral arteriogram before recommending bypass surgery."
"Advances in digital subtraction techniques have made the arteriogram far safer and quicker than it was decades ago."
Regular plural; used when referring to multiple images or multiple instances of the procedure.
"Comparing arteriograms taken a year apart showed the stent had remained open."
That 'gram' at the end is pure Greek for 'something written' — so every arteriogram literally lets doctors read your arteries like a page.

Etymology of arteriogram
Arteriogram combines the Greek-derived element 'arteria' (artery) with '-gram', from Greek 'gramma', meaning something written or recorded — the same suffix seen in telegram and diagram. The combining form reflects the modern scientific convention, established in the nineteenth century, of naming recorded images after the structure they depict. Its sibling terms include arteriography (the imaging technique), angiogram (any blood-vessel image), and venogram (a vein image). The word entered English as medical X-ray imaging developed in the late nineteenth and early twentieth centuries.

How arteriogram is actually used
Arteriogram is a technical term used almost exclusively in medical and clinical contexts. In everyday clinical speech, 'angiogram' has largely become the more general and more frequently used term, with 'arteriogram' retained when arterial imaging is meant specifically. The related noun 'arteriography' refers to the imaging technique itself rather than the resulting image.
Easily confused with arteriogram
An angiogram images any blood vessel (arteries, veins, or lymphatics), whereas an arteriogram specifically images arteries.
A venogram is an X-ray of veins using contrast dye, while an arteriogram is the corresponding imaging of arteries.
