title: The effect of projection in esophageal transit scintigraphy.
abstract: Data from esophageal transit scintigraphy with swallowing of Tc-99m sulfur colloid in water in the supine position were studied to determine the effect of posterior as compared with anterior imaging. Net attenuation was less with the anterior projection. Nonetheless, the posterior projection is favored because of more uniform attenuation.
