C T (Computed Tomography)
CT Scans: What to Expect — A Patient Resource
A CT (Computed Tomography) scan is an advanced imaging tool that allows physicians to view detailed images of the inside of your body. Before arriving for your appointment at our Imaging Center, please take a moment to review the following information to help you prepare.
What Is a CT Scan?
Also known as a “CAT scan,” CT combines multiple X-ray images to produce a two-dimensional cross-section view with as much as 100 times more clarity than a conventional X-ray. CT imaging is used to clearly show soft tissue like the brain, as well as dense tissue like bone. The information gathered during a CT scan is processed by a computer and interpreted by a radiologist to diagnose or rule out injury or disease.
How to Prepare for Your CT Scan
- Patient Instructions: You may be asked to avoid eating or drinking for several hours prior to your scan, depending on the area being evaluated. Some medications may also require temporary adjustment. Please follow the preparation guidelines provided by your referring physician or our staff.
- What to Wear: We recommend wearing comfortable, loose-fitting clothes. You may be provided with a gown for your exam, depending on the body part being scanned.
- Metal-Free Policy: Remove all metallic items—such as jewelry, eyeglasses, hairpins, or dentures—before the scan, as they may distort the imaging results.
- Contrast Agents: Some CT scans require the use of contrast material to improve image clarity. It may be administered orally, via IV injection, or rectally, depending on the diagnostic need.
During the CT Scan
- Scan Process: You will lie on a motorized exam table that gently moves through the CT scanner. It’s essential to remain as still as possible during the procedure for accurate image capture.
- Length of Exam: The actual scan is brief, typically lasting just a few minutes. However, the entire visit may take 30 to 60 minutes to allow for preparation and post-scan monitoring if needed.
- Scanner Sounds: You may hear clicking or whirring noises as the machine operates—these sounds are part of the normal scanning process.
After Your CT Scan
- Image Review: Your scan will be interpreted by a board-certified radiologist. A detailed report will be sent to your referring doctor, who will go over the results with you during a follow-up visit.
- Post-Scan Activity: Most patients can resume their normal activities immediately unless otherwise instructed.
- Your Safety and Well-Being:
CT imaging is a safe and noninvasive procedure. The amount of radiation used is low and carefully managed to minimize risk while maximizing diagnostic value.
If you are pregnant, may be pregnant, or have allergies—particularly to contrast dye—please notify our staff before your scan.
At our Medical Imaging Center, your comfort and care are our top priorities. If you have any questions before your CT scan or need help understanding your instructions, don’t hesitate to contact us. We’re here to support you every step of the way.
