Abstract:
Objective To evaluate the degree of invasion of placental implantation by quantitative delin-eation of MRI placental bed abnormal hyperplasia vessels by 3D-Slicer software.Methods Fifty-seven pa-tients with placenta implantation requiring MRI in Quanzhou Maternal and Child Health Hospital from July 2020 to December 2023 were retrospectively collected and divided into the penetrating placenta implantation group(n=11)and the non-penetrating placenta implantation group(n=46),and the differences of MRI mor-phological signs between the two groups were analyzed.Among them,37 patients with placental bed xenogenic vessels scanned by MRI were screened and there were 11 cases in the penetrating placental implantation group and 26 cases in the non-penetrating placental implantation group.3D-Slicer software was used to delineate the surface area and volume of placental bed xenogenic vessels,the differences between the two groups were ana-lyzed.Results There were significant differences in the surface area and volume of xenogenic blood vessels in placental bed between the two groups(P<0.05).The large surface area of xenogenic vessels in the placental bed was an independent risk factor for penetrative placental implantation,and the predicted area under the curve(AUC)of penetrative placental implantation was 0.927.When the surface area of the placental bed was 1 079.25 mm2,the sensitivity was 81.8%and the specificity was 88.5%.Conclusion According to 3D-Slicer soft-ware,the diagnostic efficacy of placental bed allogenic blood vessel surface area for penetrating placental implanta-tion is high.The larger the allogenic blood vessel surface area is,the deeper the placental invasion of uterus is.
