This systematic review looked at the evidence for the diagnostic thinking efficacy and therapeutic efficacy of computed tomography (CT) and (magnetic resonance imaging) MRI in temporomandibular joint disorders (TMJD).  Medline, the Cochrane Library databases and reference list of review articles were searched. Publications considered relevant were interpreted with the aid of the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tool and publications that critically evaluate systematic reviews.

Only one study was judged relevant. This study evaluated evidence of the efficacy of MRI in the diagnosis of disc position and configuration, disc perforation, joint effusion, and osseous and bone marrow changes in the temporomandibular joint, but no publication reported diagnostic thinking efficacy or therapeutic efficacy.

The authors concluded:

the absence of studies on the therapeutic efficacy of MRI and CT on TMJD reinforces the need for investment in decision-making studies; meanwhile, sectional imaging tests should be prescribed with caution, especially when health budgets are limited.
