Open magnetic resonance imaging (MRI) systems have a configuration that allows for imaging women with POP in different positions. Herein, we use a 0.5 Tesla open MRI to obtain supine, seated, and standing images. We then compare these images to evaluate the impact of posture on detection and staging of POP.<h4>Methods</h4>Women presenting with symptoms of POP at a tertiary care university hospital were asked to participate in this prospective cohort study. Symptom scores, POP-Q staging and three-position MRI imaging of the pelvis data were collected. The pubococcygeal line (PCL) was used to quantify within-patient changes in pelvic organ position as defined by: no displacement, &lt;1 cm inferior Canadian Urological Association journal = Journal de l'Association des urologues du CanadaE20-E24https://www.ebi.ac.uk/biostudies/studies/S-EPMC8937594biostudies-literatureStanding open magnetic resonance imaging improves detection and staging of pelvic organ prolapse.PMC8937594Locke JAAbdulaziz MLazare DKavanagh AMacnab AStothers LfalseStanding open magnetic resonance imaging improves detection and staging of pelvic organ prolapse.<h4>Introduction</h4>The role of imaging in pelvic organ prolapse (POP) assessment is unclear.
