title: [Fetal thoracic MRI].
abstract: Fetal thoracic MR includes the study of the lungs and the mediastinum. Fetal lungs are T2 hyperintense because of their high water contents and are clearly delineated. Their volume can be measured with MR and normal data have been published. The evaluation of the fetal lung volume is of paramount importance in the case of suspected pulmonary hypoplasia. MR is contributive in the analysis of diaphragmatic hernias to assess the diagnosis, to detail the herniated abdominal contents and in a less extent, to predict outcome. In most of the cases, MR does not provide additional information (compared to US) in the evaluation of bronchopulmonary sequestrations or congenital cystic adenomatoid malformations. Pulmonary arteries and veins are currently poorly visualized. MR seems to be an accurate modality to assess the diagnosis of esophageal atresia.
