CT掃描是一種進階版的X光檢查系統，它利用X射線和計算機技術的結合産生身體的水平或軸向圖像（通常稱爲切面）。CT掃描可以顯示身體不同部位的詳細圖像，包括骨骼、肌肉、脂肪和器官。CT掃描比标準X射線更立體，其掃描顯示出的器官或組織更爲清晰可見。

Ultrasound   imaging uses soundwaves to produce pictures of muscles, tendons, ligaments   and joints throughout the body. It is often the gold standard to diagnose   sprains, strains, tears, and other soft tissue conditions. Ultrasound is   safe, noninvasive, and does not use radiation. For orthopedic and sports   injuries your pain often occurs only when you are moving. The ultrasound   allows the doctor to visualize the body while you are moving the joint in   real time, allowing a much more accurate and functional diagnosis.
