Prenatal diagnosis of placental accretism: findings and role of ultrasound and magnetic resonance: Cases report from university hospital of Fundación Santa Fe de Bogotá (Colombia). Rev Colomb Obstet Ginecol [online]. 2014, vol.65, n.4, pp.346-353. ISSN 0034-7434.  https://doi.org/10.18597/rcog.38.

Objective: To describe and review the relevant findings of the prenatal diagnostic imaging approach in patients placenta accreta diagnosis. Materials and methods: We present 3 cases of women with risk factors for placenta accreta assessed prenatally at a high-complexity hospital, using ultrasound (US) and magnetic resonance imaging (MRI), with histopathological confirmation of the diagnosis. Clinical and imaging findings are described, together with their histological correlation. A search of the literature was conducted through PubMed, LILACS, and Ebsco, including original papers, topic reviews and case reports on the use and more important aspects of US and MRI in the prenatal diagnosis of placenta accreta. Results: 11 Original articles, 8 Review articles and 1 case report from our country were included. Placenta accreta is an obstetric pathology that threatens the health of the mother and fetus. Placenta previa associated to placental gaps in US and intraplacental hypointense bands and uterine bulge in MRI are considered as the major signs of accretism. US with color Doppler has 97 % of sensitivity and 92 % of specificity, MRI defines uterine and neighboring organs compromise (s = 77-89.6 %, e = 92 %). Conclusion: Early prenatal approach through noninvasive diagnostic imaging plays a usefull role providing information about the compromise and extention in patients with risk factors for placental accretism.
