Congenital high airway obstruction syndrome (CHAOS) is a rare life-threatening disease and prenatal diagnosis is essential. Some characteristic features seen on fetal MRI are well-known: primary lesion (upper airway obstruction) and secondary changes (dilated trachea, flattened/inverted diaphragm, enlarged and hyperintense lung). It is also reported that these secondary changes may be reduced if tracheoesophageal fistula (TEF) is present. The aim of this study is to evaluate the accuracy of fetal MRI in the prenatal diagnosis of CHAOS by comparing results with those of normal fetuses. Read More
