Computerized Tomography (CT) Scan
A computerized tomography scan (CT scan) combines data from a series of X-rays to create detailed, cross-sectional images of soft tissues, blood vessels, and bones. Our state-of-the art CT scanners can help doctors detect diseases and injuries and assist in the creation of treatment plans.
A CT scan is helpful in detecting internal bleeding after an accident. It can also help to diagnose bone disorders, cancer, heart disease, and blood clots. If you have been diagnosed with cancer, heart disease, or another condition, a CT scan can help determine how you are responding to treatment.
The imaging has also been shown by UTHealth Houston Neurosciences research to be effective in determining thrombectomy treatment in stroke patients.
What Happens During a Computerized Tomography (CT) Scan?
During a CT scan, you will lie on a table that will slowly move into a doughnut-shaped scanner that rotates around your body. Unlike a traditional X-ray, a CT scan sends a series of narrow beams through the body. A sophisticated computer constructs 3D images with the results.
It is typically a quick and painless procedure, but you might hear buzzing or whirring. You will be able to communicate with a technician via an intercom. You might be asked to hold your breath momentarily to produce clearer images.
Certain CT scans require that you digest or get injected with a contrast dye so that doctors can better see soft tissue. Some people might be allergic to the contrast material, but reactions are usually mild. Patients are briefly exposed to ionizing radiation during CT scans, however, the low dose has not been shown to cause any long-term negative effects. Pregnant patients are typically given MRIs or ultrasounds, when possible.
A UTHealth radiologist will interpret your results and send a report to your doctor.
