1-12. FLUOROSCOPY
Fluoroscopy shows the heart in action and is used more often than other x-ray methods in cardiologic examinations. Fluoroscopy is used to look for abnormal configuration, tumors, and calcifications in the heart, aorta, and pulmonary vessels, to find congestion of the lungs, and to detect pleural or pericardial effusions. During examination of the heart under fluoroscopy, barium is given by mouth so the outline of the esophagus can be seen. An enlarged left atrium pushes the esophagus aside as it becomes larger. There is no preparation of the patient for this examination.
