CT stands for computerized tomography. It is a non-invasive and painless procedure that uses a series of X-rays taken at slightly different angles of your body, to produce a detailed picture.
The images are taken while you lie on a bed that moves forwards and backwards through the scanner. In some instances a special dye may be injected into your shoulder to help improve the quality of the image.
CT scans provide good images of both bones and soft tissue areas, and can be especially useful in identifying tears or lesions in tendons, ligaments and cartilage, as well as any bone loss or anatomic abnormalities that may affect your treatment.
A CT scan is not suitable for you if you are pregnant or think that you might be pregnant.
