“…The MRI offers a complete view of the placenta and besides that the possibility to visualize the maternal pelvic organs in relation the uterus and placenta [17]. When the placenta is in posterior position, or for other reasons making it difficult to visualize, such as maternal obesity, MRI may play an important role, in addition to evaluation of when morbid adherent placenta (accrete, increta, and percreta) is suspected [58].…”

“…The accuracy (based on expert opinion) of bladder invasion is very high, as well as the accuracy of the placental bulge [63]. Indirect signs include placental heterogeneity and asymmetric shape, and with lower accuracy, T2 hypo intense parenchymal bands in the perpendicular, hyper vascularization with very abnormal, tortuous intraparenchymal vessels, and enlarged pelvic veins [17].…”

“…Стадия 2: преобладает на 32-35 неделе беременности. При нормально протекающей беременности в третьем триместре можно визуализировать более выраженные зоны гиперинтенсивного МР-сигнала на Т2-ВИ вдоль базальной мембраны, что является отражением процесса нормального старения плаценты и не должно интерпретироваться как патологические изменения [13].…”

Background. Currently, one of the topical issues of prenatal magnetic resonance imaging is accurate and timely diagnosis of pathological conditions of extrafetal structures of the fetus. In particular, the most acute problem is the need to improve the diagnostic accuracy of recognition and differentiation of placental adhesive-invasive pathology (PAIP). In the literature, there is no unified approach to the methodology and description of MRI examination of the placenta. Objective. To improve the diagnostic methods of the method of magnetic resonance imaging for the study of the placenta. Design and methods. A total of 293 MRI studies of the small pelvis of pregnant women aged 22 to 45 years (average — 35 years), in gestational age from 14 to 38 weeks (average 36 weeks) were performed and analyzed. Results. A clinical three-stage method of MRI of the placenta and an algorithm for systematized description of MRI of the placenta of pregnant women have been developed and implemented. Conclusion. The developed systematic approach to the study of the placenta will help improve the capabilities of the MRI method for examining the placenta in connection with the demand for accurate and correct interpretation of this organ in vivo.

“…However, the accuracy of MRI and ultrasound diagnosis of placenta accreta is controversial. In addition, many patients may not have access to a high-risk prenatal diagnosis center for antenatal examination [7][8][9]. The early accurate risk assessment of placenta accreta would identify high-risk women for targeted early prevention.…”

Objective The present study investigated whether first trimester mean arterial blood pressure (MAP) differed among pregnancies with placenta accreta and healthy pregnancies. Methods We recruited 152 pregnant females from 1 January 2016 to 30 January 2020 in the Affiliated Hospital of Jining Medical University in this study, including 41 cases of placenta accreta pregnancies and 111 cases of BMI- and age-matched healthy pregnant controls. First trimester MAPs were acquired from laboratory data files of the Affiliated Hospital of Jining Medical University. Multiple logistic regression analysis was used to analyze the probable risk predictor of placenta accreta. Results The performance of MAP was lower in healthy pregnancies. The MAP of the placenta accreta group was significantly higher than that of the control group (p = 0.001 < 0.05). Our results also showed that MAP was significantly positively associated with placenta accreta after adjusting for age, BMI, fertilization type, gestational week at time of blood pressure measurement, and previous cesarean section history (odds ratio [OR]: 1.11; 95% confidence interval [CI]: 1.04–1.69; p = 0.0013 < 0.05). In addition, smoking during pregnancy (OR: 7.57; 95% CI: 1.41–40.72; p = 0.018 < 0.05) and previous cesarean section history (OR: 2.57; 95% CI: 1.19–5.54; p = 0.016 < 0.05) were significantly positively associated with placenta accreta. Conclusions Increased first trimester MAP was significantly positively associated with placenta accreta, suggesting the potential role of MAP in identifying high-risk pregnancies for placenta accreta. Smoking during pregnancy and previous cesarean section history may be risk factors for placenta accreta.
