- Imaging
- • An abdominal ultrasound study to view the gall bladder area without exposure to x-rays can confirm that the
- gall bladder wall has thickened and provide information about the size and characteristics of any mass in the
- region.
- • Swallowing pills with dye that travels to the gall bladder, enabling it to be seen on x-ray (oral
- cholecystography), or the injection of dye into the bile ducts through the skin followed by an x-ray of the area
- (percutaneous cholangiography) may be done because of symptoms or an elevated serum bilirubin level. While
- both studies may document an abnormality within the bile ducts or gall bladder, neither can reliably distinguish
- between inflammation of the gall bladder (cholecystitis) and gall bladder cancer.
- • A CT scan may help determine the extent of the tumor within the gall bladder bed and the possible
- involvement of other organs.
- • Magnetic resonance imaging (MRI) may be helpful in determining if the cancer can be surgically removed, but
- it is usually not necessary because the CT scan shows similar information.
- • If the diagnosis of cancer is confirmed or suspected, a chest x-ray should be obtained. A finding of tumor
- nodules in the lungs would mean that the disease is already metastatic.
