'aortographic' originates from Greek/Neo-Latin components: 'aorta' (from Greek 'aortē') + the combining form '-graphic' (from Greek 'graphein' meaning 'to write' or 'to record').

'aorta' came into English via Latin from the Greek 'aortē'; the compound form 'aortography' (imaging/recording of the aorta) was created in the era of radiographic and angiographic techniques in the late 19th to early 20th century, and 'aortographic' developed as the adjectival form from 'aortography'.

Initially the root 'aorta' named the great artery (from Greek), and with the development of radiographic techniques the compound came to mean 'pertaining to imaging/recording of the aorta'; 'aortographic' now specifically means 'relating to such imaging or its results'.
