           What is a CAT scan?
The name stands for computerized axial
technology.
A more advanced procedure of an x-ray.
Involves a computer to give doctors cross
sectional views and also 3-D images of
different structures of the body and also
internal organs.
      How does the CAT Scan work?

A computer process these images to give
cross-sectional pictures of the body, called
tomograms.
In each of these tomograms they show an
“x-ray slice” of the body.
A collection of these “slices” can be added
to produce a 3-D picture of the body to be
studied.
      What is the use for a CAT Scan?

To find to find abnormal and normal structures in
the body and helps to accurately guide the
placement of instruments or treatments.
To analyze internal structures of the body.
Can identify head injuries, blood clots, tumors,
and problems in the spine and skull.
Can measure bone density to evaluate
osteoporosis accurately.
                Benefits

Painless
Can greatly help doctors locate
abnormalities within the body.
Can guide radiologists in performing
biopsies if cancer is suspected, removing
body fluids for different types of tests.
Doing so can greatly reduce the need for
surgery and yet will accomplish the same
goal.
            Some of the Risks

Very low risk, however some minor side
effects, (itching, rashes, etc.). However
medications are commonly used to treat
these.
Patients with kidney failure, diabetics or
ones who are constantly dehydrated were
denied CAT Scans. BUT, today’s
improvements have eliminated the
problems those faced.
              In Conclusion…..

This device has greatly advanced the science of
medicine and how doctors can diagnose certain
problems in patients.
Many surviving cancer patients have been
through this procedure and rid or minimized the
effects of cancer.
Many patients with cancer, blood clots and
osteoporosis have had their lives saved due to
the doctors using the tomographs to analyze the
problem.
