The contrast material used in the diagnosis of esophageal atresia is –: (A) Gastrograffin, (B) Conray 420, (C) Dianosil, (D) Myodii
Answer is C. Dianosil is used in oesophageal atresia, as in most cases it is frequently associated with tracheo-oesophageal fistula; so on instillation of contrast media, there is a risk of flooding in the lungs.
