CT Scan
Also known as a “CAT scan,” CT (Computed Tomography) combines multiple x-ray images to produce a two-dimensional cross-section view of anatomy with as much as 100 times more clarity than conventional x-ray.
CT imaging usually takes less than 30 minutes and is used to clearly show soft tissue, like the brain, as well as dense tissue, like bone. The information gathered during a CT scan is processed by a computer and interpreted by a radiologist to diagnose, or rule out, disease.
Concord Imaging Center offers one of the most advanced 32-row CT scanners available today. This advanced generation of equipment not only provides exceptional diagnostic accuracy, it also features advanced automatic exposure controls (AEC). Combined with the dose modulation techniques used by our technologists, we are able to effectively reduce radiation exposure to the patient while maintaining precise image quality.
Prior to the start of your CT exam, the technologist will explain the procedure to you and address any concerns you may have. Some CT exams require the injection of a contrast agent in order to view specific types of anatomy. You will be informed in advance if any special preparation is needed.
If you are scheduled to receive IV X-ray dye and had a previous allergic reaction to the dye, please tell your doctor, the radiologist or the technologist. Your doctor will need to prescribe medications to be taken the day before and day of the scan.
What can I expect when I have my CT scan?
The technologist will bring you into the CT
scan room where the procedure will be
explained to you. The technologist will help
you onto the cushioned table. As the procedure
begins, you will hear a whirring sound as the
X-ray tube moves in the machine. The table
will move slightly as each picture is taken. To
obtain the best possible images, it is important
that you lie very still during the exam.
Depending on the type of examination you
are having, you may receive an intravenous
(IV) injection of contrast material (X-ray dye).
Sometimes scans are performed prior to
receiving X-ray dye and then repeated after
the dye is a given. In either case, the
technologist will explain each step of the
examination.The technologist will communicate
with you during your exam through a
microphone. You may be given "breathing"
instructions during your exam.
