DE: deep endometriosis; MRI: magnetic resonance imaging; R: rectum; RS: rectosigmoid. NS: statistically not significant result (). Adenomyosis was not assessed against surgical reference standard because only 1 patient had a hysterectomy, vaginal DE not was computerised since none of the 10 lesions were detected on the trainee imaging, and rectovaginal septum DE not was computerised due to low prevalence (2 nodules in the 1st block, 1 lesion in the 2nd block, 1 lesion in the 3rd block).
