CT is an examination where x-ray is used to visualize
the body in thin slice. The result is that the body’s
interior will be displayed in detail. This examination
involves putting the patient on a table, that will
move into a donut shaped equipment (gantry). Only
a small fraction of the examination time is used to
acquire images. The majority of the examination time
is used to instruct & ready the equipment for
your examination. It is only during the acquisition
portion of the examination that you need to keep still.
You can relax during the rest of the examination.
Our staff will tell you when is the acquistion portion
of the examination. You will also notice the table
moves & a light on the gantry will brighten during
the acquistion portion of the examination.
At times, your doctor or the radiologist, will recommend
a contrast examination. This is usually done after
the non-contrast study. With the contrast study, a
dye (contrast) will be injected into one of your veins
(usually on the back of your hand). This contrast
contains iodine. Iodine is a substance that can cause
allergy. Allergy can induce a variety of reactions
in an allergic person. These individuals usually,
but not necessarily, have history of allergy against
shell fish, or drugs. If you have any of these allergic
history, please tell our staff. Unfortunately, not
all patients with iodine allergy have pre-existing
history of allergy. Fortunately, the contrasts we
use are new generation of contrast. These contrast
should have less allergic potential.
During the injection of contrast, you may feel a
warm sensation coming up your arm. This is due to
the injection of a warmed contrast. Then, you may
feel a warm sensation in the rest of you body. This
is a normal reaction. Later, you may have a fishy
taste at the back of your mouth. This is also a normal
If you are uncomfortable during the examination,
for any reason, please alert our staff.
