Diagnostic Tests

Your doctor may suggest the following tests to get a clearer picture of what is happening inside your shoulder. Tests may include:

• X-rays. These images can show fractures, arthritis, dislocation or other bone problems in the shoulder.
• Arthrocentesis (aspiration). In this procedure a needle is inserted into a joint to remove fluid. Arthrocentesis is used for diagnosis as well as for treatment of some shoulder problems.
• Injections. Lidocaine may be injected into a bursa (def.) or shoulder joint. If symptoms are relieved, this will help confirm a diagnosis.
• Electromyogram (EMG). This test uses a device called an electromyograph to record electrical activity and evaluate function in muscles or nerves.
• Computer tomography scan (CT scan). The CT scan involves use of special x-ray equipment to obtain image data from different body angles. The data then are processed to show a cross-section of body tissues and organs. A CT scan can help visualize bone problems in the shoulder.
• Magnetic resonance imaging (MRI). Strong magnetic fields and radio waves are used to create a cross-sectional image of the affected shoulder area. An MRI may be used to visualize soft tissue injuries such as torn rotator cuff or tendonitis.
  • MR Arthrogram. A medical dye is injected into the shoulder and an x-ray is taken of the area. This test is used in conjunction with an MRI to help identify shoulder problems such as a torn rotator cuff or labral tear (def.).
• Arthroscopy. This minimally invasive surgical procedure is used to examine the shoulder as well as to treat shoulder problems.
