[Pelvimetry]

It has been shown that, in all the different ways of performing pelvimetry, use of computed tomographic techniques leads to a significant reduction in radiation doses. We describe a new method of pelvimetry, involving computed tomography consisting of two scoutviews. The results of this method are compared with the results of conventional technique ad modum Fernström, measured in 55 women. Both methods showed large inter-observator differences. No statistically significant differences between the methods were revealed but the anteroposterior outlet was slightly smaller with the CT-technique (mean 6 mm). The method is recommended, since it is easy to use, and the rate of ionizing radiation is low.
