Possible Complications

Complications are rare, but no procedure is completely free of risk. If you are planning to have a CT scan, your doctor will review a list of possible complications, which may include:

• Allergic reaction to contrast material
• Damage to the kidney from contrast material
• Small risk of radiation exposure. Note: A CT scan is not usually recommended if you are pregnant.

Factors that may increase the risk of complications include:

• Allergies (if you are given a contrast dye during the test)
• Kidney problems (if you are given a contrast dye during the test)

Be sure to discuss these risks with your doctor before the test.

After the test, call your doctor if any of the following occurs:

• Symptoms of allergic reaction (eg, hives , itching, nausea, swollen or itchy eyes, tight throat, difficulty breathing)
• Any other concerns

In case of an emergency, CALL 911immediately.
