Oral Cholecystogram Index
Featured: Oral Cholecystogram Main Article
Oral cholecystogram (OCG) is a procedure that diagnoses gallstones. After the patient has ingested iodine-containing tablets, the iodine is absorbed into the bloodstream, removed from the blood by the liver, and excreted into the bile. The iodine outlines gallstones outside of the bile ducts. Risks of OCG include exposure to radiation and allergic reaction to iodine.
