A
Computed Tomography or CT scan creates very clear
two-dimensional images of the brain and other parts of
your body that cannot be seen on regular X-rays. The
images are produced by projecting small amounts of
X-rays through the part of the body being examined and
converting the information into images by using a
special computer. For some CT scans, the radiologist
injects a contrast medium or dye to highlight certain
tissues for closer examination. This type of scan helps
differentiate between healthy and diseased tissue,
making it possible to accurately diagnose many diseases
in their early stages.
• You will be asked to arrive 15 minutes prior to your
scheduled appointment.
• Remove metal and plastic items from the part of your

• Let our staff know what medications you are taking.
