  • Biopsy and Radiofrequency Ablation Procedures

  • Computed Tomography is sometimes used to help perform a procedure, such as a biopsy or radiofrequency ablation.

    • What is a CT guided procedure?
      A CT guided procedure may consist of a biopsy, in which a small sample of tissue from inside your body is obtained using the CT machine for guidance. This technique will often save you from having to have an operation to get the same piece of tissue. A radiofrequency ablation is a separate procedure which is performed to treat a tumor.
    • Why is this being done?
      A biopsy is performed because a previous radiology test showed an abnormality. It is not clear what the abnormal tissue is, and a small sample of tissue is required to find out.
    • Does it hurt?
      We use local anesthesia (like Novocaine at the dentist) for all biopsies. In certain situations we will administer sedation to make you sleepy during the test. You will not be completely asleep for this test.
    • How long does a CT procedure take?
      The actual procedure is approximately one hour. You will be observed in our recovery area by qualified nurses for approximately three hours after the procedure.
    • Do I have to do anything special before having a CT procedure?
      Special preparations are required of patients up to one week before the procedure. Ask your doctor for information on preparations for your specific procedure. Click here for more information..
    • How will I get the results of the biopsy?
      The specimen obtained from the procedure will be delivered to pathology where specialized doctors will look at the tissue under a microscope. They will send the results to your doctor in approximately three to five days.
