What is CT?
A CT scan is a diagnostic imaging procedure that uses x-rays and a computer to produce images through the body.
These images of the body are much more detailed than general x-rays.
How does CT work?
CT uses x-rays to generate images from different angles and levels of the body. The x-ray tube actually circles around inside the round donut shaped tube while images are being taken, compared to traditional general x-rays where the x-ray tube is stationary.
What types of procedures are available at MCHHS?
- Cervical, Thoracic, Lumbar Spine
- Facial Bones
What happens during the exam?
The technologist begins by positioning the patient on the CT table. The table will move slowly into the CT scanner “donut” and depending on the area that is being scanned, the increments of movement maybe so small that they are almost undetectable or large enough that the patient feels the sensation of motion.
What’s the preparation for the test?
Please arrive 15-20 minutes early, so you can check in for your exam. Some exams require the patient to be fasting and to drink barium prior to arriving for the exam. Your physician’s nurse will inform you of these instructions.
Some CT exams do require an IV, so contrast can be given to highlight blood vessels.
