Hepatobiliary Scan

Hepatobiliary scans demonstrate gallbladder function. The patient will be injected with 99m Tc Choletec. Once on the table, periodic images will be taken over the course of one hour. Additional images may be needed after the first set of images is taken, and can take up to 4 hours. Patients having a hepatobiliary scan must not eat anything 6 hours before their scheduled appointment. No pain medication should be taken the day of the study. Opiate medications such as morphine, Demerol, and Codeine may result in a false positive.
