Magnetic resonance imaging of the female bony pelvis: MRI pelvimetry.

Magnetic resonance imaging (MRI) was used for the evaluation of the bony pelvis in 4 pregnant and 10 non-pregnant women. The anatomical details and shape of the bony pelvis were easily examined and the main pelvic measurements were estimated on the sections and programs. The end points were easily demonstrated. There was no need to correct for magnification. The study confirmed that MRI is a very valuable technique for assessment of the pelvis. Although it is expensive, it overcomes the technical difficulty of the other methods used for pelvimetry.
