Diagnostic Imaging Services
Computed Tomography (CT) is also commonly known as Computerized Tomography
(CT) or Computed Axial Tomography (CAT). Basically, CT is an advanced
x-ray system that generates a number of detailed cross-sectional images
of all parts of the body. Studies are routinely performed on the head,
spine, chest, abdomen, pelvis, and extremities as well as on the venous
and arterial systems within the body. These sophisticated studies are
produced by placing the patient on a table and rotating a focused x-ray
beam around the patient which captures images from many angles.
All CT examinations are performed with the patient changing into a procedure
gown and laying on a table that moves on an automated track through the
opening of the gantry. The gantry is the device that holds the x-ray tube
that will circle around the table. The technical staff will explain everything
to you prior to starting the examination. The particular procedure that
you are having may involve the injection of contrast material through
a vein in your arm and the technical staff will explain that process to
you as well.
During the procedure, you will feel the table move and you will hear the
sound of the tube as it rotates around you. The technical staff will talk
to you through a microphone from the control room during the procedure.
It is important that you follow the instructions given by the technical
staff during the procedure (such as holding your breath when asked) and
remaining as still as possible.
Most CT procedures only last a few minutes and you should experience very
little if any discomfort during the procedure.
Many CT examinations do not require specific patient preparation prior
to having the study performed. However, there are examinations that do
require specific preparation guidelines and those will be reviewed with
you when the examination is scheduled. The preparations are generally
dietary restrictions but can involve activities such as drinking oral
contrast material prior to the time of your appointment.
Procedure Side Effects / Complications
Side effects can occur during a CT examination. These are generally mild
and are related to the contrast material. If you receive an injection
of contrast material through a vein in your arm, you may experience a
warm sensation throughout your body, the feeling of needing to urinate,
and possibly a metallic taste in your mouth – all of which pass
fairly quickly. Oral contrast material may cause slight changes in bowel
movements which should soon return to normal.
Some patients may experience a complication to the injection of contrast
material and develop an allergic reaction. Allergic reactions may result
in itching, sneezing, hives, or other allergic symptoms. In more rare
cases, the contrast material may trigger anaphylaxis, a life-threatening
allergic reaction in which the airway can become swollen enough to restrict
breathing. In such cases, emergency treatment is administered immediately.
Patients that have diabetes or other renal diseases may require special
care due to the involvement of the kidneys filtering contrast from the
Patients are encouraged to discuss any and all allergies they may have
with their physician prior to having a CT scan.
