Patient Preparation for CT
Computed tomography (CT) uses X-rays to create highly detailed images of internal organs. Since CT scanners are capable of rotating the X-ray device, they can image detailed cross sections, called “slices,” of areas of the body. Unlike images from conventional X-rays, CT shows details of all tissues including organs, bones, blood vessels, etc.
Please follow instructions below. Proper preparation is important for a good examination and your personal comfort. Please bring your referral form, photo ID, medical insurance, and a complete list of all current medications with you at the time of your examination.
