Simultaneous radionuclide angiocardiography and esophagography is a useful technique for evaluating the cardiac silhouette and mediastinal masses in children with congenital heart disease.
99mTc-pertechnetate angiocardiography performed simultaneously with radionuclide esophagography (barium-sulfate-99mTc-pertechnetate mixture) was used to rule out a mediastinal mass in a child with known congenital heart disease. The mass proved to be the left atrium. This technique is useful in evaluating the cardiac silhouette as well as mediastinal masses.
