For a long time diagnostic imaging has been used in planning radiation treatment for the carcinoma of the cervix, although it is not the essential part of FIGO staging work up. In the past, treatment planning was based on examination under anesthesia (EUA) findings and standard portals were used. Various studies have shown high risks of geographical miss and/or inappropriate tumor coverage (up to >70%) with the use of standard portals, which was related to poor local control. Increasingly, diagnostic/planning CT and MRI imaging are used to plan radiation treatment.
