X-ray pelvimetry in a breech protocol: a comparison of digital radiography and conventional methods

X-ray evaluation of the pelvis plays a pivotal role in selecting term breech presentation for a possible trial of labor. Even minimal degrees of disproportion may have disastrous consequences for the aftercoming head. Our evaluation of x-ray pelvimetry by computerized tomography scanning suggests it is probably more accurate than conventional methods, with a concomitant decrease in fetal x-ray exposure.
