Reasons for Test
A CT scan is done to look at the organs and tissue in the abdomen. The doctor will look for signs of:
- Injury
- Tumors
- Infections
- Other diseases
The doctor may recommend an abdominal CT for symptoms such as:
- Abdominal pain
- Bowel changes or blockages
- Problems passing urine, including bleeding
- Yellowed skin color
- Weight loss
- Unexplained fever
- Abdominal injury
- Fluid buildup in the abdomen
Possible Complications
Problems are rare, but all procedures have some risk. The doctor will go over some problems that could happen.
Sometimes a chemical called contrast is used to improve the pictures. Some people can have an allergic reaction or kidney problems caused by the contrast. This is rare.
A CT scan uses radiation. It may not be advised for people with certain conditions such as pregnancy.
Be sure to discuss these risks with the doctor before the test.
