CT (CAT) Scan > Exams & Procedures > CT Extremity

A CT of the extremity is performed to evaluate the bones and soft tissues of the arms, legs, wrist, hands, and feet. CT is an excellent diagnostic tool and is able to provide the radiologist with many different views of the extremity for review.

Will I need to have a needle?

Maybe. You may require an injection of intravenous contrast, which may be needed to evaluate blood vessels and tumours. You may feel a warm sensation throughout your body after the injection of the contrast, and you may experience a metallic taste in your mouth. These sensations are normal and disappear after a few minutes. The technologist will discuss the injection with you before the scan is completed, and will be pleased to answer any questions you may have.
