A computer Tomography (CT) scan is a precise, simple and safe examination that creates a cross-sectional image of a specific anatomical part of the body. A thin beam of x-rays is read and recorded by an electronic detector, then fed into a computer. The computer constructs an image based on the data, which then may be transferred to film. Contrast media are substances given intravenously or orally to assist in viewing a particular area.
Houston Methodist Willowbrook Hospital has 2 state-of-the-art 64-slice CT scanners with the ability to perform a wide array of specialized procedures. These scanners provide detailed images of the anatomical system in just seponds and allow for quick interpretation and diagnosis. With four times as many detectors as a typical multi-detector CT scanner, the 64-slice scanners provide sharp, clear, three-dimensional images, including 3-D views of the blood vessels. They gather high-resolution images of a heart, brain, or a pair of lungs in about five seconds; a scan of the whole body takes about 30 seconds. This new technology minimizes radiation dosage to patients, especially children.
Also within the Houston Methodist CT department are dedicated computer workstations that allow for advanced specialized post-processing for 3-D imaging. CT of the Coronary Arteries provides unsurpassed visualization that was previously only available during an invasive cardiac catheterization procedure.
There are two CT scanners for prompt patient care and rapid work-in of urgently needed imaging studies for unscheduled outpatients.
The CT Department provides comprehensive services, including needle aspiration and biopsy and other invasive procedures. A radiologist is on-site to monitor and guide the CT diagnostic, interventional, and therapeutic procedures.
CT scans can be performed on an outpatient basis, unless they are part of a patient's inpatient care. Although each hospital may have specific protocols in place, generally, CT scans follow this process:
You should wear comfortable, loose-fitting clothing for your CT scan. Avoid clothing with snaps or zippers. The arrival time for your appointment will be based on the type of CT scan you are having. Some exams require that you drink a contrast material 1–2 hours prior to your exam. How you prepare also depends on which part of your body is being scanned. You may be asked to remove your clothing and dress in a hospital gown. You will also need to remove any metal objects such as jewelry that might interfere with the image results. If you are required to have a contrast material before you scan, it is usually to help emphasize blood vessels or other structures while blocking others. You will either have the contrast material by injection, mouth or enema. If your test involves contrast medium, your healthcare provider may ask you not to eat for 4 to 6 hours before the test because the contrast medium can cause nausea.
Inform your technologist if you:
If there is a chance that you may be pregnant, notify your healthcare provider and/or x-ray technologist
The procedure requires a few basic steps, although some aspects may vary depending on the examination you will be receiving.
The length of the examination will vary from ten minutes to forty-five minute, depending upon the specific examination requested by your physician.
Although CT is an effective diagnostic tool, certain medical conditions may exclude its use. Please inform your physician and his staff at the time of scheduling if any of the following apply to you:
