'aortogram' originates from Greek and New Latin medical formation, specifically from the Greek word 'aortē' (meaning 'aorta') combined with Greek 'gramma' (meaning 'a written record' or 'something written').

'aortogram' was formed in modern medical English by compounding 'aorta' + '-gram' (from Greek 'gramma'), producing a term used in medical imaging to denote a recorded image of the aorta.

Initially, it meant 'a recorded image or tracing of the aorta', and over time it has retained this technical meaning in radiology and related fields.
