A ct scan
is a study which allows one to see the body in cross section.
X-rays are used in this scan, and using a sophisticated computer,
by sending the beams through the body in many different directions,
the cross sectional anatomy of the body is reconstructed.
A ct scan is excellent at showing detail of bone, blood
and air, but not as good with certain types of soft tissue.
A magnetic resonance imaging (mri) is much better at showing
soft tissue. The same precautions which apply to the
use of x-rays also apply to the use of ct scanning.
Pregnant women should notify their physician or ct technician.
While some patients may not tolerate a closed mri scan
because of the confined space, patients rarely
have any kind of difficulty tolerating a ct scan because the
opening is much larger, and the length of the tunnel much
