CT (Computed Tomography) Testing

CT exams gather a series of images of the body from different angles. This non‑invasive exam provides anatomical information quickly and accurately, which assists your physician in making accurate diagnosis and treatment recommendations. Antelope Valley Hospital offers 24‑hour, state‑of‑the‑art, helical computed tomography (CT) with a skilled technologist and radiologist available at all times.

CT testing is available for emergency trauma evaluation; severe headache or stroke; acute abdominal pain such as appendicitis and kidney stones; and for evaluation of arteries, veins and heart chambers. It’s also a vital tool for the workup and monitoring of cancer patients, and for evaluation of complex fractures, visual problems, sinus disorders and lung diseases.


G.E. VCT 64 Slice CT Scanners

Our Radiology Department is home to two advanced 64 slice CT scanners. Volume coverage speeds up the scan process which makes it a highly effective imaging option in emergency, trauma and acute care situations. Higher speed scanning translates to clearer, sharper images with fewer problems caused by patient movement or motion of a beating heart. Also, the scanner performs CT angiography to help physicians evaluate the arteries, assess their function, observe anatomy and detect the degree of coronary of heart disease. Automated dose‑reduction features means less exposure to radiation.


How do I prepare?

Different tests require different preparations. You shouldn’t eat for at least four hours before your scan. While you can expect to be in the Radiology Department for 1‑1/2 to 3 hours, the actual scan takes much less time. You may be asked to drink an oral contrast agent approximately 90 minutes before your scan. If I.V. contrast is ordered by your physician, you may, for a short time feel a slight warm sensation in your body. This is normal.

What should I expect?

The CT machine looks like a large square doughnut and only covers the area that is being examined. Before entering the scanning room you may be asked to remove anything metallic. Once you’re positioned on the table, the scan will begin. During the exam you will be in the room alone; however, your technologist will be able to see and hear you throughout the whole procedure.
