To do an<unk> , an iodine-containing dye (meglumine ioglycamate) is injected<unk> ly into the blood. The liver then removes the dye from the blood and excretes it into the bile. The iodine is sufficiently concentrated as it is secreted into the bile that it does not need to be further concentrated by the gallbladder to outline the bile ducts and any gallstones that may be there. The gallbladder is not always seen on an<unk> , as the iodine-containing bile may bypass the gallbladder entirely and empty directly into the small intestine.
