Overview
A Computerized Tomography (CT) Scan allows doctors to visualize internal structures using x-ray images taken from multiple angles. These images are combined to create clear cross-sectional slices of various body parts. Unlike typical x-rays, a CT scan provides a more detailed view that can reveal conditions such as, but not limited to:
Spinal Injuries: It helps identify fractures or dislocations resulting from trauma or accidents.
Degenerative Disc Disease: It can show disc herniations or bulges that might be causing nerve compression.
Spinal Stenosis: It reveals narrowing of the spinal canal or neural foramina, which can compress the spinal cord or nerves.
Tumors: It helps in detecting tumors or masses within the spine or surrounding structures.
Infections: It can identify infections of the spine such as osteomyelitis or discitis.
Congenital Anomalies: It shows any structural abnormalities present since birth.
Preparation
Before undergoing a CT scan, you will need to remove items such as glasses, jewelry, and other metal objects. Additionally, you might receive a contrast dye orally or through an IV needle to enhance the scanner’s ability to visualize internal structures clearly.
The Scan
To begin your scan, you will lie on a table that slides into the CT scanner, which is shaped like a ring. When the scan starts, you will hear buzzing, clicking, and whirring noises. The table will slowly move through the scanner. It is important to remain perfectly still to ensure clear imaging. A typical scan lasts about half an hour. Any movement during the scan can result in blurry images and may require a repeat scan. A technician in an adjacent room will monitor you and the imaging process. They will communicate with you through a speaker to provide updates during your scan.
Review
After your CT scan is completed, you can go home. Doctors will review the images and discuss them with you during a follow-up appointment.
