angiogram

The term 'angiogram' is a modern medical compound built directly from ancient Greek roots. The first element, 'angio-', originates from the Greek angeion, which broadly meant a vessel, receptacle, or container. In medical terminology, it was specialized to refer specifically to the vessels of the circulatory system. The second element, '-gram', derives from the Greek gramma, meaning a letter, drawing, or written record. The compound thus literally translates to "a record of vessels." This logical construction perfectly captures the procedure's essence: creating a visual record, typically an X-ray image, of the body's vascular network by using a contrast agent to make the vessels visible.
