Digital radiographs obtained with a CT scanner were evaluated as an alternative to conventional pelvimetry. Dosimetry studies demonstrated an absorbed radiation dose of 22 mrad for each digital radiograph, approximately 3% of the dose for comparable standard radiographs. Distance measurements were accurately made on digital radiographs and axial CT sections by cursor placement and a computer program with no need to correct for magnification. Clinical studies of 10 patients confirmed that pelvimetry using digital radiographs is an accurate, simple, and extremely low-dose precedure which could replace the conventional method.
