Diagnosing Shoulder Conditions

X-ray - a diagnostic test which uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film

Arthrogram - a test in which dye is injected into the shoulder joint and X-rays are taken to outline structures of the shoulder. When the fluid leaks into an area that it does not belong, disease or injury may be considered, as a leak would provide evidence of a tear, opening or blockage

Magnetic resonance imaging (MRI) - a diagnostic procedure that uses a combination of large magnets, radiofrequencies and a computer to produce detailed images of organs and structures within the body; can often determine damage or disease in a surrounding ligament or muscle

Computed tomography scan (CT or CAT scan) - a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat and organs. CT scans are more detailed than general X-rays

Electromyogram (EMG) - a test to evaluate nerve and muscle function

Ultrasound - a diagnostic technique which uses high-frequency sound waves to create an image of the internal organs

Laboratory tests - to determine if other problems may be the cause

Arthroscopy - a minimally-invasive diagnostic and treatment procedure used for conditions of a joint. This procedure uses a small, lighted, optic tube (arthroscope) which is inserted into the joint through a small incision in the joint. Images of the inside of the joint are projected onto a screen and used to evaluate any degenerative and/or arthritic changes in the joint, to detect bone diseases and tumors or to determine the cause of bone pain and inflammation
