Computerized Tomography (CT)

Computerized Tomography, also known as CT scans or CAT scans, are painless diagnostic tests that use specialized X-ray equipment and powerful computers to create cross-sectional images of the inside of the body &/or the head. Using CT technology, doctors can quickly obtain detailed information about internal structures without surgery and with little or no discomfort to you. CT scans provide more detail than conventional X-rays and can produce images of bone, soft tissue and blood vessels all at the same time.

At Texas Health Presbyterian Hospital – WNJ, we have the technology to perform most CT scans — from routine chests, abdomens, renal stones, to more complex biopsies and reconstruction procedures. In cases of trauma, the speed and accuracy of CT can help save lives.

To display the GI tract, you may be asked by your technologist to drink a "contrast" drink that will allow the radiologists on the medical staff to differentiate between bowel loops and surrounding tissues. You may also be given intravenous (IV) fluid with another form of "contrast" that allows the blood vessels in the body to be seen. If your CT procedure is ordered with IV contrast, you will be required to have a lab test prior to the procedure in order to responsibly ensure your kidneys are functioning within normal limits. The contrast is safely injected through an IV system during the procedure. This contrast has elements of iodine, so if you have any allergies please inform the technologist as soon as you can.

Texas Health Presbyterian Hospital - WNJ is currently equipped with two CT scanners; a state-of-the-art GE VCT Lightspeed 32-slice located at the main hospital and a GE 4-slice located at the POB, and provides CT service 24 hours/day.

Overall Benefits of CT:

CT is one of the best tools for studying the chest and abdomen because it provides detailed, cross-sectional views of all types of tissue
A major advantage of CT is that it is able to clearly show very small bones as well as surrounding tissues such as muscle and blood vessels all at the same time
CT scans help to confirm the presence, size and location of a tumor
CT imaging can play a significant role in the detection of and care for vascular diseases

Patient Benefits of CT:

CT scanning is painless, noninvasive and accurate
CT examinations are fast and simple; in emergency cases, they can reveal internal injuries and bleeding quickly enough to help save lives
Unlike an MRI, a CT scan can be performed if you have an implanted medical device of any kind
After a CT scan, no radiation remains in your body
