| Popis: | In recent years, with the development of ultrafast sequences, magnetic resonance (MR) imaging has been established as a valuable diagnostic modality complementary to ultrasonography (US). MR imaging offers several technical advantages over US, including a larger field of view, fewer limitations due to maternal habitus, and the ability to visualize fetal anatomy regardless of fetal presentation. The authors discuss the most frequently found thoracic abnormalities, including congenital diaphragmatic hernia, congenital cystic adenomatoid malformation, bronchopulmonary sequestration, bronchogenic cyst, congenital high airway obstruction syndrome, and bronchial obstruction by a mucus plug, specifically with respect to the effect of fetal MR imaging on diagnosis and treatment. MR imaging can assist in establishing the prognosis and in perinatal management, especially in the case of congenital diaphragmatic hernia, which is the most common indication for thoracic MR imaging. MR imaging can demonstrate hernial contents and quantify lung volume better than US, allowing the prognosis to be determined and postpartum extracorporeal membrane oxygenation needs to be estimated. MR imaging can also be used to distinguish different types of cystic adenomatoid malformations, identify the anomalous vessels of pulmonary sequestration, and assess the functional effects of bronchogenic cysts. Balanced sequences (steady-state free precession sequences) allow performance of unenhanced thoracic vascular studies, which are useful in the diagnosis of intralobar or extralobar sequestration. In summary, fetal MR imaging can provide additional data useful in establishing prognosis and in perinatal management of thoracic malformations. |
