cholecystography

 [ko″le-sis-tog´rah-fe]
radiography of the gallbladder, using a radiopaque dye as contrast medium. adj., adj cholecystograph´ic. The purpose of the examination is to determine the ability of the gallbladder to fill, concentrate bile, and empty. The dye is administered in tablets the evening before the x-ray films are made. Other, more commonly used diagnostic tests are discussed at gallbladder.

cho·le·cys·tog·ra·phy

(kō'lē-sis-tog'ră-fĕ),
1. Radiographic study of the gallbladder after oral administration of a cholecystopaque.
2. Scintigraphic imaging of the gallbladder and central bile ducts after administration of a radiopharmaceutical secreted by the liver.

cholecystography

[kō′lisistog′rəfē]
an x-ray examination of the gallbladder. At least 12 hours before the study the patient has a fat-free meal and ingests a contrast material containing iodine, usually in the form of tablets. It may also be given intravenously. The iodine, which is opaque to x-rays, is excreted by the liver into the bile in the gallbladder. After the procedure the patient consumes a fatty meal or cholecystokinin, which stimulates the gallbladder to contract, expelling bile and contrast material into the bile duct. Additional x-ray films are taken about 1 hour later. The test is useful in the diagnosis of cholecystitis, cholelithiasis, and tumors and in the differential diagnosis of a mass in the upper right quadrant of the stomach.

cholecystography

A method for visualising the gallbladder and biliary tract, based on excretion of iodinated radiocontrast via the biliary tree after oral ingestion.
 
Indications
Suspected gallbladder disease (e.g., cholecystitis, cholelithiasis, upper right quadrant colic); the method has fallen into disuse and been all-but replaced by gallbladder ultrasonography.

cho·le·cys·tog·ra·phy

(kō'lĕ-sis-tog'ră-fĕ)
Radiographic study of the gallbladder after oral administration of a cholecystopaque or scintigraphic imaging of the gallbladder and central bile ducts after administration of a radiopharmaceutical secreted by the liver. An obsolete technique.

cholecystography

X-ray of the gall bladder, usually facilitated by the use of a contrast medium, so that gallstones can be readily seen.
