Tests

Orthopedic specialists rely on medical history, physical exams and diagnostic tests to determine the cause and severity of orthopedic conditions.

Common imaging tests include the following.

• X-rays use a small amount of radiation to produce a two-dimensional picture of bones.
• Computerized tomography (CT) scan images show soft tissues, such as ligaments or muscles, more clearly than conventional X-rays. CT scans produce detailed, cross-sectional pictures of internal structures in the body.

• 	An MRI is particularly useful for detecting soft tissue damage.

  Magnetic resonance imaging (MRI) is an advanced tool to diagnose diseases not seen on conventional X-rays. MRI can produce high-quality images without using radiation. MRI uses a sophisticated computer, a strong magnetic field and radio waves. The patient lies on a padded table and moves into the center of the scanner. The machine makes knocking sounds when the images are taken. During the procedure, patients must lie very still. The exam is painless and usually lasts about one hour.
