| Chole- | bile |
| -docho | ducts |
| Choledocho- | pertaining to the common bile duct |
| Cholecyst- | pertaining to the gallbladder |
| Cholelithiasis | formation or presence of gallstones in the gallbladder or bile ducts |
| Cholecystitis | inflammation of the gallbladder |
| Cholecystopaque | a type of contrast used to visualize the gallbladder and bile ducts |
| Cholecyst | gallbladder |
| -lith | stone |
| -iasis | full of |
| Cysto | bag or sack |
| Choledocholithiasis | formation or presence of gallstones in the common bile duct |
| Biliary tract examinations are performed to evaluate what? | liver function, patency and condition of the ducts, concentrating and emptying power of the gallbladder, presence of gallstones. |
| Technical consideration for biliary tract imaging include: | small FSS, close collimation, short exposure time, soft tissue technique (70-80kVp), expose after exhalation. |
| Operative cholangiography indications include: | investigate bile duct patency, sphincter of oddi function, reveal the presence of caliculi, demonstrate intraluminal neoplasms, demonstrate stricture or dilation of ducts. |
| Patient position for operative cholangiography: | supine, RPO (15-20 degrees), C-arm centered over the inferior rib margin. |
| Structures shown during operative cholangiography: | biliary system full of contrast, branches of the hepatic duct, pancreatic duct, no extravasation of contrast, contrast emptied into the duodenum, any retained gallstones. |
| ERCP stands for: | endoscopic retrograde cholangiopancreatography |
| Define endoscopic retrograde cholangiopancreatography: | procedure used to diagnose biliary and pancreatic pathologic conditions. |
| When can an ERCP be done? | when the bliary ducts are not dilated, there is no obstruction, there is indication of abnormalities on previous exam, if no pseudocysts are present in the liver. |
| Briefly explain an ERCP procedure | under conscious sedation, a fiber optic endoscope is passed through the mouth and duodenum. A cannula is then passed through the endoscope and into the ampulla of vater; contrast is pushed into the common bile duct. |
| Why might oblique radiographs be done for an ERCP? | to prevent overlap of the common bile duct and pancreatic duct. |
| Explain the different types of contrast used on an ERCP | dense contrast opacifies small ducts well but obscures small stones. Dilute contrast is used to visualize small stones. |
| What exam is usually done prior to an ERCP? | ultrasound for pseudocysts |
| How can we see the layering of stones in the gallbladder? | on a Rt lateral decub |
| Name the essential projections of the gallbladder | PA, LAO, Rt lat decub |
| What study involves the injection of contrast directly into the common bile duct? | ERCP |
| How long does it take for the ducts to empty following an ERCP? | 5 minutes |
