Quantitative pelvic organ mobility assessment in supine and upright position for assessment of pelvic organ prolapse

Quantitative pelvic organ mobility assessment provides fundamental insight into pelvic organ prolapse (POP). However, this is currently only performed in supine position. In this case study the assessment is performed both in supine and upright position using a tiltable MRI scanner. The displacement of the cervix during contraction is larger in upright than in supine position. During straining the displacement in supine position is 15-20 mm whereas in upright position hardly any displacement occurs. This may indicate that, in upright position, the cervix already reaches its maximum extent at rest. Upright mobility assessment seems to give supplementary information in POP.
