is a CT scan?
CT scan (also known as "CAT SCAN" for (computed Axial tomography)
is a diagnostic test that combines the use of x-rays with
computer technology. A serices of x-ray beams from
many different angles are used to create cross-sectional
images of the patient's body. These images are assembled
in a computer into a three-dimensional picture that can
display organs, bones, and tissues in great detail.
of the two CTs at Upper Michigan's Regional Medical Center
is a spiral CT, which scans more quickly and clearly
than conventional CT scanning.
spiral CT has an option called CTA (CT Angiography), which
produces a 3-D image of the arteries and veins. For some
patients, CTA can be used in place of angiography, which
is more invasive.
