Background . Magnetic resonance imaging (MRI) is a highly informative and safe method of examination during pregnancy, which helps to identify and localize pathological changes in the uterus or placenta. Objective . The goal of the study was to develop a universal topographic-anatomical segmentation of the pregnant uterus using MRI (with possible comparison with the bony landmarks) to determine the exact localization of abnormalities in the placenta and myometrium. Design and methods . A retrospective analysis of 96 MR images of the pelvis of pregnant women with various abnormalities in the placenta or myometrium was carried out. Results . The results of the analysis were used to develop a universal topographic and anatomical segmentation of the pregnant uterus by a step-by-step division of the entire area of the uterine walls into 12 conditionally equivalent segments. The sides of the uterus were marked with the capital letters D (Dexter — right), A (Anterior — anterior), S (Sinister — left), P (Posterior — posterior) to define the orientation, and with lowercase abbreviations sup (=superior), med (=median) and inf (=inferior) to specify the upper, middle and lower levels, respectively. Conclusion . MRI-based DASP segmentation analysis of MR images allows to accurately localize uterine abnormalities and can be used in clinical practice by radiologists and obstetricians when considering the delivery method.
