Osteoarthritis (OA) is a widely prevalent disease worldwide and, with an
increasing ageing society, is a challenge for the field of physical and
rehabilitation medicine. Technologic advances and implementation of sophisticated
post-processing instruments and analytic strategies have resulted in imaging
playing a more and more important role in understanding the disease process of
OA. Radiography is still the most commonly used imaging modality for establishing
an imaging-based diagnosis of OA. The need for an effective non-surgical OA
treatment is highly desired, but despite on-going research efforts no
disease-modifying OA drugs have been discovered or approved to date.
MR imaging-based studies have revealed some of the limitations of radiography. The
ability of MR to image all relevant joint tissues within the knee and to
visualize cartilage morphology and composition has resulted in MRI playing a key
role in understanding the natural history of the disease and in the search for
new therapies. Our review will focus on the roles and limitations of radiography
and MRI with particular attention to knee OA. The use of other modalities (e.g.
ultrasound, nuclear medicine, computed tomography (CT),
and CT/MR arthrography)
in clinical practice and OA research will also be briefly described. Ultrasound
may be useful to evaluate synovial pathology in osteoarthritis, particularly in
the hand.
