Computerized tomography (CAT scan) — also called CT — combines
a series of X-ray views taken from many different angles and computer
processing to create cross-sectional images of the bones and soft tissues
inside your body.
Your doctor will be able to look at each of these slices individually or
perform additional visualization to view your body from different angles.
In some cases, CT images can be combined to create 3-D images. CT scan
images can provide much more information than do plain X-rays. A CT scan
can be used to visualize nearly any parts of the body.
The patient lies on the exam table while the table moves slowly through
a "donut" shaped scanner while X-rays pass through the body,
creating individual images that can be combined to provide three dimensional
images. Some exams require the patient not eat for a few hours prior to
the exam. Sometimes an oral prep (solution to drink) is given prior to
the exam, and some patients will receive an IV injection during the procedure.
Technologists are able to see the patient and communicate with them throughout
the exam. The procedures usually take between 15 and 30 minutes.
We feature a GE Lightspeed 16-slice CT scanner that generates thin cross-sectional
images of the body. The associated computer combines those slices into
highly detailed 3-D images. This enables our radiologists to obtain the
information they need to assist in the diagnosis of diseases and life
threatening illnesses including strokes. The procedure is non-invasive,
with minimal radiation exposure. We have the capability of doing CT Angiography
and CT guided biopsies on outpatients in a hospital setting with radiology
nurses assisting the radiologist in the procedure when indicated.
