Developed method of three-plane magnetic resonance pelviophetometry.

Background. Magnetic resonance pelviophetometry is a highly informative, non-invasive and safe method for assessing the size of the pelvis of a pregnant woman and the fetal head, but it has several disadvantages — a long scanning time, heating of the tissues of the pregnant woman and the fetus, and operator dependence.Objective. Evaluation of the capabilities of the three-plane 3D Dixon MR-pelviophetometry (3D MR-PFM) technique, its comparative analysis with the generally accepted method of two-plane 2D MR-pelviophetometry (2D MR-PFM).Design and methods. A retrospective analysis was perormed out in 26 pregnant women with risk for the development clinically narrow pelvis for various reasons. Results. The data obtained using the Dixon pulse sequence is comparable to the data obtained during the standard technique.Conclusion. The Dixon sequence can be used for the developed 3D method of MR pelviophetometry, since it allows to reduce the scanning time and, according to statistical analysis, show comparable results.
