Time of optimal gallbladder opacification with telepaque (lopanoic acid).

Abstract

The time to peak visualization of the gallbladder was recorded in a series of 47 patients Previously, fourteen hours had been given as the time of maximum opacification after ingestion of Telepaque. A range of fourteen to nineteen hours was demonstrated as giving peak opacity in this series. These findings allow greater latitude in the arrival of patients in the x-ray department.
