This imaging process evaluates the bile flow and pooling through the liver, ducts, gallbladder and intestines. The imaging is performed through intravenously injecting the tracer into the bloodstream, to be later received by bile producing cells and then expelled into the hepatic ducts. Fasting: Is required for no less than 6 hours and no more than 24 hours. Medication contradiction: Narcotics should be withheld for 24 hours and a list of medications should be provided as some may cause an interference with the results. Tracer administration: The radiopharmaceutical will be injected intravenously. Examination duration: The imaging process will take up from 45 minutes up to one hour. Imaging will be conducted immediately after the tracer is injected, in certain cases you may be requested to ingest a fatty meal (which will be provided by the center) 15 minutes later and the imaging will be resumed for additional 50 minutes. Additional related examinations: In certain occasions additional images may be required 4 hours later to the study.
