Commonly Tests Of Knee

Commonly Tests Of Knee

X-Ray (radiography)

A procedure in which an x ray beam is passed through the knee to produce a two-dimensional picture of the bones.

Computerized axial tomography (CAT) scan

A painless procedure in which x rays are passed through the knee at different angles, detected by a scanner, and analyzed by a computer. CAT scan images show soft tissues such as ligaments or muscles more clearly than conventional x rays. The computer can combine individual images to give a three-dimensional view of the knee.

Bone scan (radionuclide scanning)

A technique for creating images of bones on a computer screen or on film. Prior to the procedure, a harmless radioactive material is injected into your bloodstream. The material collects in the bones, particularly in abnormal areas of the bones, and is detected by a scanner.

Magnetic resonance imaging (MRI)

A procedure that uses a powerful magnet linked to a computer to create pictures of areas inside the knee. During the procedure, your leg is placed in a cylindrical chamber where energy from a powerful magnet (rather than x rays) is passed through the knee. An MRI is particularly useful for detecting soft tissue damage.

Arthroscopy

A surgical technique in which the doctor manipulates a small, lighted optic tube (arthroscope) that has been inserted into the joint through a small incision in the knee. Images of the inside of the knee joint are projected onto a television screen.

Joint aspiration

A procedure that uses a syringe to remove fluid buildup in a joint, and can reduce swelling and relieve pressure. A laboratory analysis of the fluid can determine the presence of a fracture, an infection, or an inflammatory response.

Biopsy

The examination of a piece of tissue under the microscope.
