MR defecography: comparison of HMO system measurement between supine and lateral decubitus patient position.

Background: Pelvic floor dysfunction (PVD), a prevalent clinical issue impacting quality of life, can be effectively assessed using magnetic resonance defecography (MRD) with the patient either supine or in the lateral decubitus position.

Purpose: To compare the measurement value and grading in dynamic MRD within the closed-magnet system of PFD patients performed in supine versus lateral decubitus position using the H line, M line, and organ prolapse (HMO) classification system.

Material And Methods: During 2017-2019, 100 patients with PFD underwent MRD during defecation in both supine and lateral decubitus positions.
