Computed Tomography (CT)
A CT scan, also known as a CAT scan, is a medical imaging procedure that uses X-rays to create detailed images of the inside of your body. Unlike a standard X-ray, a CT scan takes multiple images from different angles, allowing doctors to see a cross-sectional or "slice" view of your bones, tissues, and organs.
During the procedure, you lie on a table that slides through a large donut-shaped machine called a CT scanner. An X-ray beam rotates around your body, sending out radiation. Detectors inside the machine pick up the X-rays that pass through your body and convert them into electrical signals. A computer then uses these signals to create detailed images of your body.
CT scans are relatively quick, usually taking just a few minutes. They can provide detailed images of your entire body, including your bones, tissues, and organs.
Uses of CT Scans:
Head Injuries: To check for bleeding, fractures, or other brain damage.
Chest Problems: To diagnose pneumonia, emphysema, or lung cancer.
Abdominal Problems: To diagnose appendicitis, liver disease, or kidney stones.
Cancer: To detect and monitor cancer.
Bone Injuries: To diagnose fractures, dislocations, or other bone problems.
What to Expect During a CT Scan:
You will be asked to remove any metal objects, such as jewelry, watches, and glasses.
You will lie on a comfortable table that slides into the CT scanner.
The machine will make a soft whirring noise during the scan.
In some cases, you may be given a contrast dye to help improve the visibility of certain structures.
You will be asked to hold very still during the scan, which can take anywhere from a few seconds to a few minutes.
Tips for a Successful CT Scan:
Wear comfortable clothing. You may be asked to change into a hospital gown before your scan.
Inform your doctor if you have any allergies, especially to iodine.
Tell your doctor about any medical conditions you have and any medications you are taking.
Do not eat or drink anything for a few hours before your scan, if instructed.
Overall, CT scans are safe and effective medical imaging tools that can help your doctor diagnose a variety of medical conditions. If you have any questions about CT scans, please talk to your doctor.
