A CT (Computed Tomography) scan in orthopaedics is a specialised imaging method used to get detailed pictures of bones, joints, and surrounding soft tissues. It employs X-ray technology and computer processing to create cross-sectional images, offering a precise view of the musculoskeletal system.
Orthopaedic CT scans are sometimes needed for diagnosing bone and joint disorders, planning surgical procedures like joint replacements, assessing complex fractures, and evaluating the progression of degenerative diseases like arthritis.
CT scans involve exposure to more radiation than regular X-rays but are safe under controlled conditions. Inform your doctor if you are pregnant. The benefits of accurate diagnosis and treatment planning usually outweigh the risks of radiation.
You’ll lie on a table that slides into the CT scanner, a large doughnut-shaped machine. The scanner rotates around the targeted area, capturing detailed images. Staying still during the scan is crucial for high-quality images. The process is quick, often taking just a few minutes.
Preparation may vary based on the area being scanned. You might need to remove metal objects and wear a hospital gown. In some cases, a contrast dye is used to enhance image clarity, which may require fasting or drinking a special solution before the scan.
Post-scan, you can typically resume normal activities immediately. If contrast dye was used, hydration is recommended to help eliminate it from your body. Your orthopaedic specialist will review images to guide your treatment plan.
CT scans in orthopaedics are an invaluable tool, providing detailed insights into bone and joint health. They assist in accurate diagnosis, treatment decisions, and surgical planning. If you have concerns about the procedure, don’t hesitate to discuss them with your orthopaedic care team.
