PET Scan with Whole Body CT Scan

Combining these two imaging tests help create detailed images of your organs. The images show their size and shape and how well they are functioning.

Combining these two imaging tests help create detailed images of your organs. The images show their size and shape and how well they are functioning.

A positron emission tomography (PET) with Computed Tomography (CT) scan uses two types of imaging to create detailed images of structures in your entire body. One type (PET) uses a radioactive substance that is absorbed into tissues and shows the degree that those organs are using energy. The second type (CT) is a series of X-rays.

  • When these forms of imaging are combined, they reveal details about the size and shape of structures and how much energy they are using.
  • When done together these imaging procedures can check for different diseases and help monitor patients for the status of certain types of cancers.

So that appropriate precautions are taken, be sure to tell the technician if you are pregnant or could be pregnant or if you are breast-feeding.

  • Tell your healthcare provider about the medicines you take, any allergies you have and any recent imaging studies you have had.
  • Your healthcare provider will tell you how to prepare for the test. You will probably be told not eat or drink anything except water for several hours before the test.
  • The radioactive substance will be injected into a vein in your arm. You will then wait about an hour for the substance to be absorbed by your tissues.
  • You must lie very still during the exam because moving could blur the images.

This care path's costs include the facility charges (the test or procedure) plus the physician charges (interpreting the test or performing the procedure). You may get separate bills for the facility and physician charges.

What should I ask my healthcare provider before having this test?

  • Is there any special preparation for the test? (If so, get clear instructions on what you need to do.)
  • Why are you ordering this test? Will the test results change my treatment plan? If not, do I need the test?

X-ray helps consumers determine the average cost of common medical procedures in their location. By gathering and analyzing data from leading insurance providers across the US, patients can compare the estimated price of common medical procedures to determine their approximate out-of-pocket expenses. All rates are approximations and not guarantees based on data that is available to the consumer. There are currently 638 procedures available in our database. These results and the information contained within should in no way take the place of actual medical advice.
