What is a CT Scan?
A CT scan, also known as a CAT scan, is a diagnostic imaging procedure that uses X-ray technology to create detailed images of the inside of your body. Unlike traditional X-rays, a CT scan produces cross-sectional images, providing a more comprehensive view of your organs, bones, and blood vessels.
How Does a CT Scan Work?
A CT scanner is a large, doughnut-shaped machine. You lie on a table that slides into the center of the scanner. As the machine rotates around you, it takes multiple X-ray images. A computer then combines these images to create detailed cross-sectional pictures.
When is a CT Scan Used?
CT scans are used for a variety of reasons, including:
- Diagnosing injuries or infections
- Detecting tumors or other abnormalities
- Guiding procedures like biopsies or surgeries
- Monitoring the effectiveness of treatment
- Evaluating internal bleeding
Preparing for a CT Scan
The preparation for a CT scan depends on the specific part of your body being examined. Your health care provider will give you detailed instructions. In some cases, you may have dietary restrictions or avoid certain medications before the scan.
The CT Scan Procedure
During the CT scan, you will lie on a table that slides into the CT scanner. You may be asked to hold your breath for short periods. The scan itself is usually quick, but the total time for the procedure may vary.
After the CT Scan
There is typically no special care required after a CT scan. You can resume your normal activities unless otherwise instructed by your healthcare provider. The radiologist will interpret the images and send a report to your doctor.
