Patient Selection and Eligibility:
Patients were selected through screening of electronic hospital patient records in Healthcare Information eXchange (HiX) (ChipSoft BV, Amsterdam, the Netherlands), based on electronic search queries in CTcue (CTcue BV, Amsterdam, the Netherlands). Relevant search terms are presented in Supplementary File A.
Women were eligible for inclusion if they underwent a hysterectomy due to benign pathology in our centre between 2007 and March 2022 and had pre-operative pelvic MRI available. Subjects were included regardless of symptoms. Subjects were excluded if: they did not have a pelvic MRI prior to hysterectomy, they had an unsuitable MRI protocol (see appendix B for further specification), they were post-menopausal (due to no longer active disease), had a gynaecological malignancy or if no pathology report available after hysterectomy. Patients were also excluded if they explicitly stated in their file that they did not want their information to be used for research purposes.
