Imaging produces pictures (images) of the inside of your body. The pictures can help your doctor understand what is happening and choose the right treatment. Different imaging techniques use different types of energy (see each topic for more information):

  • CT scan uses x-rays to make a digital image.
  • MRI uses radio waves and a strong magnetic field to create a 3-dimensional image.
  • Ultrasound creates an image from sound waves.
