X-ray pelvimetry was performed on 19 subjects using computed radiography (CR) and on 100 sub­jects using a conventional screen/film (SF) system. CR enables the accurate identification of measuring points through image processing at a low dose; the accuracy obtained with CR in predicting the rela­tionship between cephalopelvic disproportion and subsequent cesarean section was better than that with the conventional system. CR is an important new radiological examination modality whereby better images can be obtained at a lower dose, thereby drastically reducing the radiological expo­sure to both mother and fetus.
