IPA: /vɛnəˈɡrɒfɪ/
KK: /vɛnəˈɡrɑfi/
A medical imaging technique used to take pictures of veins after a special dye is injected to make them visible.
The doctor ordered a venography to check for any blockages in the patient's veins.
Venography → It is formed from "veno-" (from Latin "vena", meaning vein) and "-graphy" (from Greek "grapho", meaning to write or record). The word refers to the process of recording or imaging veins, typically for medical purposes.
Think of 'veins' ('veno-') being 'recorded' ('-graphy') — that's what venography means.
