What is a CT?
Computed tomography (CT) is also known as Computed Axial Tomography (CAT).
The CT machine resembles a large doughnut with a sliding table that moves
slightly during the exam. The CT exam is a painless procedure and the
technology is a sophisticated x-ray procedure. The CT technology uses
an advanced computer to compile multiple images of cross-sectional pictures
(slices) taken during the scan of the area of the interest. By using this
technology to generate images of tissue, bone and blood vessels our specialized
Radiologists can visualize and interpret any visual abnormalities present.
What is a CT used for?
CT scanning has the ability to image and compile a combination of soft
tissue, bone, organ and blood vessels to detect medical problems. It is
an invaluable tool for staging and detecting cancer. Other applications
include diagnosis and treatment of heart disease, stroke, evaluation of
vascular diseases and assessment of traumatic injuries.
Some of the exams we offer in CT imaging at MMCSC include the following:
MMCSC is a dedicated stroke center offering early detection and treatment
of stroke in the region. The CT department is staffed by our specially
trained and certified CT technologist that provides care 24 hours a day
seven days a week. The MMCSC CT Department is fully accredited by the
American College of Radiology (ACR) to provide CT imaging services.
The patient is instructed by the scheduling counselor not to eat or drink
several hours prior to the test.
The CT technologist informs the patient about the exam and gives instructions
about the procedure. The patient is asked a few questions about their
medical history and whether they have any allergies to food or medications?
The patient is then placed on the CT table and the exam is performed.
Depending on the ordered exam the patient may be required to drink oral
contrast 2 hours prior to their exam. The oral contrast allows the area
of interest to better visualize the underlying medical problems for the
The requested exam may also require an intravenous injection of contrast
material which is administered by the Radiology nurse (RN) during the
scanning process. The IV injection can enhance and delineate the area
of the study for the Radiologist.
Frequently asked questions:
How long will the CT exam take?
Depending on the exam once the patient is placed on the table the exam
can take from fifteen minutes to a half an hour to complete.
What is oral and intravenous contrast?
Depending on the exam and what you’re ordering physician requested,
the patient may be instructed to drink oral contrast approximately 2 hours
prior to the exam. Using oral contrast the interpreting Radiologist will
be able to determine the underlying medical problem.
Intravenous contrast is used to highlight blood vessels and to enhance
the structure of organs like the vessels of the brain, neck, heart, aorta,
kidney, liver, spleen and pancreas. The contrast is contained in a special
injector which is administered by our certified and highly qualified Radiology
nurses. During the procedure the CT technologists will be constant contact
with you during your exam.
Getting your results:
Your CT images will be analyzed by a radiologist, a physician who specializes
in CT testing. The radiologist will send a signed report which includes
an interpretation of the image to your primary physician. Your physician
will receive your results soon after. At MMCSC we also offer our patients
a free copy of their exam on CD to share with their physicians.
Our Team of Specialists:
Our board certified Radiologists are specially trained to diagnose and
interpret the images. At MMCSC the CT technologists are specially trained
in the theory and practice of CT procedures and operate the equipment
used during the procedure. The technologists are board certified (ARRT,
CT) and the MCSMC is fully accredited by the American College of Radiology.
