Arthrography is a technique to evaluate and diagnose joint conditions, including disease within the ligaments, tendons and cartilage. It may be indirect, where contrast material is injected into the bloodstream, or direct, where contrast material is injected into the joint. Arthrography may use Computed Tomography (CT) scanning, Magnetic Resonance Imaging (MRI) or Fluoroscopy – a form of real-time x-ray.

Direct arthrography is the preferred method because it is better for distending or enlarging the joint and imaging small internal structures, thus allowing for better evaluation of diseases or conditions within the joint.
