MR Imaging in Diagnosis of Pelvic Floor Descent: Supine versus Sitting Position

Figure 2

MR Defecography. Rest phase in sitting (a) and supine (b) position. Evacuation phase in sitting (c) and supine (d) position. The pathological fixed descent was detected only in sitting position in rest phase (a). In evacuation phase, a cystocele became evident (d), whereas the maximal descent of the ARJ is similar in both sitting and supine position (c, d). BB: bladder base; VF: vaginal fornix; ARJ: anorectal junction.
