ABSTRACT
Nuclear scintigraphic study of oesophageal transit, introduced by Kazem (1972), is a diagnostic test that examines the function of the oesophagus. It is designed to complement the anatomical data obtained though endoscopy and radiological techniques and may complement the physiological data obtained through manometry. Mechanical obstructions to the oesophagus can be identified through radiological studies and endoscopic techniques, but abnormalities in the motor function are better demonstrated by nuclear scintigraphy.
