[Dosimetry comparison of pelvimetry methods using conventional radiologic technic and x-ray scanner].

The aim of this study is to compare conventional and CT-scan X-ray pelvimetry. Doses have been measured on the surface and in deep tissues as well as total doses received by the patients. With CT the fetus and the mother were exposed to 1/10th of the total dose delivered using conventional X-rays. The method is acceptable and the high quality of the films achieved make CT-scanning pelvimetry safer than X-ray pelvimetry.
