“…The arrival of new MRI techniques has allowed a more detailed study of fetuses considering that, with faster sequences, the images acquisition can be performed during a single respiratory pause of the mother, minimizing fetal motion artifacts, besides eliminating the necessity of sedation (10-12) . The higher image resolution and contrast of MRI as compared with US allows a more accurate evaluation of the diaphragmatic lesion extent, herniated viscera and the fetal pulmonary maturity (11,12) . The present study was aimed at demonstrating the relevance of MRI and US findings for establishing the prenatal diagnosis in 14 cases of CDH.…”

OBJECTIVE: To demonstrate the relevance of ultrasonography and magnetic resonance imaging findings in the prenatal characterization and prognostic evaluation in cases of congenital diaphragmatic hernia. MATE-RIALS AND METHODS: Fourteen pregnant women (mean gestational age = 28.7 weeks) who had undergone ultrasonography for suspicion of fetuses with congenital diaphragmatic hernia were assessed by means of magnetic resonance imaging on a 1.5 tesla equipment, following the standard protocol. Two radiologists evaluated the images and the findings were defined by consensus. RESULTS: Twelve fetuses had left diaphragmatic hernia and two, right diaphragmatic hernia. Ultrasonography showed the fetal liver inside the thorax of five fetuses (three with left diaphragmatic hernia, and two with right diaphragmatic hernia) and magnetic resonance imaging in eight fetuses (six with left diaphragmatic hernia, and two with right diaphragmatic hernia). Stomach and small bowel loop herniation was observed in all of the fetuses with left diaphragmatic hernia (n = 12) at both magnetic resonance imaging and ultrasonography. Eight fetuses (seven with left diaphragmatic hernia and one with right diaphragmatic hernia) survived after surgical treatment. CON-CLUSION: Ultrasonography and magnetic resonance imaging are complementary imaging methods in the evaluation of congenital diaphragmatic hernia. Magnetic resonance imaging is a helpful diagnostic method complementary to ultrasonography for evaluation of the fetal liver positioning, considering its relevance as a prognostic factor in cases of congenital diaphragmatic hernia. Keywords: Fetus; Congenital diaphragmatic hernia; Ultrasonography; Magnetic resonance imaging.OBJETIVO: Demonstrar a significância dos achados da ressonância magnética e da ultra-sonografia na caracterização pré-natal e avaliação do prognóstico de pacientes com hérnia diafragmática congênita. MATE-RIAIS E MÉTODOS: Catorze gestantes (idade gestacional média de 28,7 semanas) examinadas com ultrasonografia e apresentando fetos com suspeita de hérnia diafragmática congênita foram avaliadas por meio da ressonância magnética. Os exames foram realizados em aparelho de 1,5 tesla usando seqüências-padrão. Dois radiologistas avaliaram as imagens e estabeleceram os achados por consenso. RESULTADOS: Doze fetos tinham hérnia diafragmática à esquerda e dois, à direita. O fígado fetal foi localizado no interior do tórax de cinco fetos pela ultra-sonografia (três com hérnia diafragmática esquerda e dois com hérnia diafragmática direita) e de oito pela ressonância magnética (seis com hérnia diafragmática esquerda e dois com hérnia diafragmática direita). Herniação do estômago e alças de intestino delgado foi observada em todos os fetos com hérnia diafragmática esquerda (n = 12), tanto pela ultra-sonografia quanto pela ressonância magnética. Oito fetos sobreviveram após cirurgia (sete com hérnia diafragmática esquerda e um com hérnia diafragmática direita). CONCLUSÃO: A ultra-sonografia e a ressonância magnética são métodos de imagens...
