A incid\u00eancia de acretismo placent\u00e1rio aumentou significativamente nas \u00faltimas d\u00e9cadas, principalmente em fun\u00e7\u00e3o da eleva\u00e7\u00e3o das taxas de cesarianas, sendo este o seu principal fator de risco. A sua identifica\u00e7\u00e3o pr\u00e9-natal precisa permite um tratamento ideal com equipe multidisciplinar, minimizando significativamente a morbimortalidade materna. Os exames de escolha s\u00e3o a ultrassonografia e a resson\u00e2ncia magn\u00e9tica (RM), sendo a RM um m\u00e9todo complementar indicado quando a avalia\u00e7\u00e3o ultrassonogr\u00e1fica \u00e9 duvidosa, para pacientes com fatores de risco para acretismo placent\u00e1rio ou quando a placenta tem localiza\u00e7\u00e3o posterior. A RM \u00e9 prefer\u00edvel tamb\u00e9m para avaliar invas\u00e3o de \u00f3rg\u00e3os adjacentes, oferecendo um campo de vis\u00e3o mais amplo, o que melhora o planejamento cir\u00fargico. Diversas caracter\u00edsticas na RM s\u00e3o descritas no acretismo placent\u00e1rio, incluindo bandas hipointensas em T2 intraplacent\u00e1rias, protuber\u00e2ncia uterina anormal e heterogeneidade placent\u00e1ria. O conhecimento desses achados e a combina\u00e7\u00e3o de mais de um crit\u00e9rio aumentam a confiabilidade do
