  • Frequently Asked Questions

    • What does a CT scanner look like?
      The CT scanner looks like a large doughnut with a narrow table. The patient lies on the table, which moves through the center of the machine. The technologist is in the next room and observes the patient through a large window.
    • Do I have to do anything special before 
      having a CT scan?
      Some scans (abdomen and pelvis) require the patient to drink about a quart of liquid prior to the scan. For certain exams, x-ray contrast also may be injected into a vein during the scan. If you are scheduled to have a test with intravenous contrast, you should not eat for four hours before the exam. You should however take all your medications with a sip of water at the regular time. 
      More about preparing for the exam.
    • How long does a CT scan take?
      The entire procedure takes 15 to 45 minutes, depending on what part of the body is being scanned.
    • Will it hurt?
      No. The scanner uses x-rays to see inside your body.
    • When may I eat after the test?
      As soon as the exam is over.
    • How will I get the results of the CT scan?
      After the scan is finished, one of our board-certified radiologists will interpret the study and send a report to your doctor within 24 hours.
