Flashcards
Cholecystitis
Cholecystitis
Inflammation of the gallbladder; when a blockage of the cystic duct restricts bile flow. Frequently caused by a stone lodged in the gallbladder neck.
Choledocholithiasis
Choledocholithiasis
Stones in the biliary ducts causing enlargement or narrowing. Diagnosed via sonography, MRI, or ERCP.
Cholelithiasis
Cholelithiasis
Stones in the gallbladder, visible as radiolucent or radiopaque densities with a 'shadowing' effect on ultrasound.

Study Notes
- Acute or chronic cholecystitis is inflammation of the gallbladder
- In acute cholecystitis, cystic duct blockage restricts bile flow from the gallbladder into the common bile duct
- Blockage occurs frequently (95% of cases) due to a stone lodged in the gallbladder neck
- Over time, bile irritates the gallbladder's inner lining, causing inflammation
- Stenosis may prevent small gallstones from entering the duodenum, obstructing the duct
- Cholecystitis and jaundice can result from biliary stenosis
- During cholangiography, the common bile duct may appear elongated, tapered, and narrowed.
- A gallstone lodged at the distal common bile duct often presents a filling defect with a small channel of contrast media around it
- Table 12.2 summarizes clinical indications for gallbladder and biliary tract radiography
Summary of Clinical Indications: Gallbladder and Biliary Tract
- Choledocholithiasis (stones in biliary ducts)
- Common Radiographic Examinations: Sonography, MRI, ERCP
- Possible Radiographic Appearance: Enlargement or narrowing of biliary ducts due to stones
- Exposure Factor Adjustment: None
- Cholelithiasis (stones in gallbladder)
- Common Radiographic Examinations: Sonography, MRI, Cholescintigraphy (radionuclide studies)
- Possible Radiographic Appearance: Radiolucent and radiopaque densities in gallbladder region; "shadowing" effect with ultrasound; failure to accumulate radionuclide within gallbladder
- Exposure Factor Adjustment: None
- Acute Cholecystitis
- Common Radiographic Examinations: Sonography, MRI, Cholescintigraphy (radionuclide studies)
- Possible Radiographic Appearance: Thickened gallbladder wall with ultrasound; failure to accumulate radionuclide within gallbladder
- Exposure Factor Adjustment: None
- Chronic Cholecystitis
- Common Radiographic Examinations: Sonography, MRI
- Possible Radiographic Appearance: Calcified plaques or calcification of gallbladder wall
- Exposure Factor Adjustment: None
- Neoplasms
- Common Radiographic Examinations: Sonography, MRI, CT
- Possible Radiographic Appearance: Mass in gallbladder, liver, or biliary ducts; extensive calcification of gallbladder wall
- Exposure Factor Adjustment: None
- Biliary Stenosis
- Common Radiographic Examinations: Operative cholangiogram, ERCP
- Possible Radiographic Appearance: Elongation, tapering, and narrowing of common bile duct
- Exposure Factor Adjustment: None
