Diagnostic Procedures

Accurate evaluation and diagnosis of orthopedic problems requires advanced medical training. Greenwich Hospital orthopedists are highly skilled in the use of the latest techniques to reach a proper diagnosis.

After a complete physical examination, medical history profile, and discussion of symptoms, patients may undergo one or more diagnostic tests appropriate for their condition. Diagnostic imaging tests are often conducted by the Greenwich Hospital Radiology Department. Following are among the tests offered at Greenwich Hospital:

  • X-ray.  A diagnostic test that uses invisible electromagnetic energy beams to produce images of internal tissues, bones and organs onto film.
  • Arthrogram.  An x-ray used to view bone structures following an injection of a contrast fluid into a joint area. Fluid leaks may indicate a tear, opening or blockage.
  • Magnetic Resonance Imaging (MRI).  A procedure that uses a magnetic field and pulses of radio wave energy to create pictures of organs and structures inside the body.
  • Computed tomography scan (CT or CAT scan).   A combination of x-rays and computer technology that creates highly detailed images of any part of the body, including the bones, muscles, fat and organs.
  • Electromyography (EMG).  A needle placed in the muscle records and analyzes the electrical activity in the muscle.
  • Ultrasound.   A diagnostic technique that uses high-frequency sound waves to create an image of the internal organs.
  • Arthroscopy.  A minimally invasive procedure in which a tiny tube fitted with miniature camera (arthroscope) is inserted into the joint to allow the surgeon to look for joint damage or disease. The arthroscope also permits reconstructive procedures on the joint, if needed.
  • Myelogram.   A test that uses dye injected into the spinal canal to make the structure clearly visible on x-rays.
  • Bone Density Test.  A test that uses x-rays to measure how many grams of calcium and other bone minerals are in a segment of bone.
