Gallstones

What are gallstones?

Gallstones (often misspelled gall stones, or gall stone) are stones that form in the gall (bile). (The gallbladder is a pear-shaped organ just below the liver and stores the bile secreted by the liver.)

  • Bile is a watery liquid made by the cells of the liver that is important for digesting food in the intestine, particularly fat.
  • Liver cells secrete the bile they make into small canals within the liver.
  • The bile flows through the canals and into larger collecting ducts within the liver (the intrahepatic bile ducts).
  • The bile then flows within the intrahepatic bile ducts out of the liver and into the extrahepatic bile ducts-first into the hepatic bile ducts, then into the common hepatic duct, and finally into the common bile duct.

From the common bile duct, there are two different directions that bile can flow.

  • The first direction is on down the common bile duct and into the intestine where the bile mixes with food and promotes digestion of food.
  • The second direction is into the cystic duct, and from there into the gallbladder (often misspelled as gall bladder).

Once in the gallbladder, bile is concentrated by the removal (absorption) of water. During a meal, the muscle that makes up the wall of the gallbladder contracts and squeezes the concentrated bile in the gallbladder back through the cystic duct into the common duct and then into the intestine. (Concentrated bile is much more effective for digestion than the un-concentrated bile that goes from the liver straight into the intestine.) The timing of gallbladder contraction-during a meal-allows the concentrated bile from the gallbladder to mix with food.

Gallstones usually form in the gallbladder; however, they also may form anywhere there is bile; in the intrahepatic, hepatic, common bile, and cystic ducts.

MRI (Magnetic Resonance Imaging Scan) »

What is an MRI scan?

An MRI (or magnetic resonance imaging) scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures. The MRI scanner is a tube surrounded by a giant circular magnet. The patient is placed on a moveable bed that is inserted into the magnet. The magnet creates a strong magnetic field that aligns the protons of hydrogen atoms, which are then exposed to a beam of radio waves. This spins the various protons of the body, and they produce a faint signal that is detected by the receiver portion of the MRI scanner. The receiver information is processed by a computer, and an image is produced.

The image and resolution produced by MRI is quite detailed and can detect tiny changes of structures within the body. For some procedures, contrast agents, such as gadolinium, are used to increase the accuracy of the images.

When are MRI scans used?
