CT stands for computerized tomography. This is a technique in which X-rays are
used to create cross sectional images of the body. At Larchmont Imaging
Associates, we use the newest type of CT scanners called Multi-Detector CT
(MDCT). Unlike older generation scanners which scans the body one slice at
a time, these scanners can allow an entire region of the body to be scanned
volumetrically in a very short period of time. The data acquired by MDCT
contains much more detail than previous generation scanners and yield greater
diagnostic information.
Unlike conventional X-ray exams, CT scanning allows direct visualization of the
inside of your body. For example, an X-ray exam of the head will only show the
bony skull while a CT scan of your head will show the brain tissue itself. The
images are displayed as a series of cross sections, or “slices” through the
head. Similarly, a CT scan of the body will directly show internal organs that
regular X-ray exams cannot. Data from an MDCT scanner can also be manipulated
to yield images in different planes of sectioning which allows greater diagnostic
information. The data can also be used to generate 3D models of various parts of
the body. One of the recent advances in radiology is the use of MDCT scanners to
perform CT angiography, a
non-invasive study to image blood vessels in the body. MDCT scanners are so fast
that we even have the capability to perform coronary CT angiography, a study that images the coronary
arteries of the heart.
Some
of the problems that CT can help diagnose are strokes, bleeding
in or around the brain, infections, tumors, and abnormally
enlarged lymph nodes. CT scanning is the best way to quickly
and accurately evaluate the chest, abdomen and pelvis. Often
when the body is scanned, and sometimes for head CT's, intravenous
contrast is used. Injection of this contrast helps in the
detection of infection and tumor sites.
What
are the advantages of CT Scanning?
CT
Scanning provides accurate and highly detailed diagnostic
information. CT can detect very small abnormalities which
allows treatment to begin when the chances for cure are
greatest. It is safe and painless and often replaces more
invasive procedures, such as angiography or exploratory
surgery. Furthermore, it is conveniently performed as an
outpatient procedure.
Who
will interpret the study?
When
your scan is completed, the results are interpreted and
analyzed by a board certified radiologist. This is a physician
who has completed at least 4 to 5 years of advanced training
after obtaining his or her medical degree. The radiologist
will provide your physician with an interpretation of the
results. Your doctor will combine the CT scan results with
other information about you, including symptoms, physical
examination, and other test results. Your physician can
then make a diagnosis and explain what the results mean
for you in terms of your health and whether or not treatment
is needed.
