Triphasic MRI of pelvic organ descent: sources of measurement error.

Purpose: To identify sources of error when measuring pelvic organ displacement during straining using triphasic dynamic magnetic resonance imaging (MRI).

Materials And Methods: Ten healthy nulliparous woman underwent triphasic dynamic 1.5 T pelvic MRI twice with 1 week between studies.

Rectal pressure response to a meal in patients with high spinal cord injury.

Objectives: To determine whether there is a postprandial increase of rectal pressure in patients with spinal cord injury (SCI) and to compare their rectal pressures with those of healthy volunteers.

Design: A before-after trial comparing SCI and control subjects.

Setting: Patients were recruited from the register of an SCI unit at a rehabilitation medicine department, and the study took place at the university hospital laboratory in Sweden.
