An CT scan can be used to image nearly every part of the body. CTs are very good at evaluating internal organs such as the liver, kidneys, pancreas and brain. They are also used to generate 3 dimensional images of bones such as the spine, ankle, and wrist. These 3D images assist in treatment and surgical planning.

CT is a relatively new technology that has rapidly advanced along with computing power. There are tens millions of CT scans done every year. Here are some commonly ordered CT scans and the sort of disease they are tailored to look for:

• CT Liver -- tumors, cysts, and cirrhosis of the liver
  
• CT Spine --degnerative disease (arthritis), fractures, bone tumors
  
• CT Brain -- stroke, tumors, bleeds, skull fractures
• CT Kidneys -- kidney stones, tumors, cysts, blockage (hydronephrosis)

What to do before your CT scan:

It helps to be prepared in advance of your appointment time. You will need to get a Radiology referral or prescription from your doctor. Check to make sure the facility you choose takes your insurance plan and your plan has authorized the CT. Get preparation instructions from the facility’s staff in advance. Many CT scans require dye/contrast.  Let the facility know if you have any kidney problems, allergies or are on medication. Although you should follow your doctor’s advice, you can choose a local imaging center to perform your CT test.

What to expect during and after your CT scan:

• The CT scan appointment may take up to 1 hour. Plan accordingly.
• Many CT scan tests will require a dye/contrast injection. An IV is placed and the dye is injected while the scanner takes pictures.
• An CT scan uses radiation, so you will be alone in the CT scan room.
• You may need to take a film or CD copy of your CT scan to your doctor.
• A physician Radiologist will interpret the CT. A report is sent to your doctor.
