Computed tomographic bioconstants of the uterine cervix

The computed tomography (CT) assessment of uterine cervix that has been used in practice till now is descriptive, utilizing only a subjective visual evaluation of the image and not allowing determination of precise densitometric reference values for it. As a result, the changes in the volume, density and structure of the cervix can only be determined approximately. In order to be objective, a CT evaluation of the volume oncological disorders of uterine cervix requires precisely determined normative densitometric values. Using accurate CT linear measurement of the density profile, the most frequent mean density, and the mean density we studied computed tomographically 139 women who presented with no pathologic changes in their uterine cervices. On the basis of the obtained information we determined the normal densitometric characteristics of the uterine cervix, that is, its CT bioconstants.
