X-rays with advanced computer processing create detailed images of the body. It is a fast, painless method to diagnose abnormalities and disease processes.
WakeMed scanners have advanced technology. This state-of-the-art technology reduces the radiation dose without compromising image quality.
Notably, WakeMed Raleigh Campus and Cary Hospital offer cardiac CT.
WakeMed Cary Hospital offers bariatric CT as well and is recognized as a Bariatric Center of Excellence with bariatric CT as part of that designation.
How the CT Scan is Performed
The technologist begins by positioning you on the CT examination table, usually lying flat on one's back, on the side or stomach. Straps and pillows may be used to help maintain the correct position and to hold still during the exam.
If a contrast material is used, it will be injected through an intravenous line (IV) into an arm vein during the procedure. A scan of the lower spine may also be done after injecting contrast material into the spinal canal (usually well below the bottom of the spinal cord) during a lumbar puncture. This will help to detect tumors or locate areas of inflammation or nerve compression.
Next, the table will move quickly through the scanner to determine the correct starting position for the scans. Then, the table will move slowly through the machine as the actual CT scanning is performed.
You may be asked to hold your breath during the scanning.
When the examination is completed, you will be asked to wait until the technologist determines that the images are of high enough quality for the radiologist to read.
The CT scanning is usually completed within 30 minutes.
