CT扫描是一种进阶版的X光检查系统，它利用X射线和计算机技术的结合产生身体的水平或轴向图像（通常称为切面）。CT扫描可以显示身体不同部位的详细图像，包括骨骼、肌肉、脂肪和器官。CT扫描比标准X射线更立体，其扫描显示出的器官或组织更为清晰可见。

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.
