The present work is based on the analysis of results of two-dimensional and three-dimensional transvaginal ultrasonography and MRI performed at 54 female patients with invasive forms of cervical carcinoma (stage IIb - IVb according to FIGO classification), in period since 2002 till 2005. Verification of the diagnosis was conducted on the base of cytological examination. For an assessment of a spread of the disease we used a complex of data, including a gynecological survey, ultrasonography, magnetic resonance imaging, computed tomography and radionuclide imaging. Ultrasonography of a cervix was performed by ''Sonoline'' (Elegra and Antares), designed by Siemens, working in a real time regimen with use of transvaginal probes (with bandwidth of 7,5–10,0 MHz). Examinations wrer performed on 5–7 days of a menstrual cycle or on a day of patient's resort in case of a menopause. On the background of the performed examinations we can make the following conclusions: 1. Comparing to the data of two-dimensional examination, a conducting of three-dimensional ultrasonography in angiographic regimen and the B-regimen allows to increase a diagnostic value of the method in disclosing an invasion in a parametrium, a myometrium and a vagina at IIb–IV stages of the disease. 2. Application of three-dimensional ultrasonography enlarges an accuracy of a staging of cervical carcinoma from 57% up to 70%. 3. A descriptiveness of the procedures of 3D ultrasonography essentially drops at IV stage of the disease because of a complicity of the visualization of the surrounding organs' involvement (an urinary bladder, a rectum), and also regional lymph nodes and pelvic bones; in that case an application of the MRI is justified.
