"MRI is the standard method of evaluation of TMJ. The study should include oblique sagittal spin and gradient echo T2-weighted images on each TMJ separately, both in open and closed mouth positions. Some institutes use PD instead of spin echo T2 sequence. Normally the disc is biconcave structure, returns low signal on all sequences, located between the condyle and temporal bone and its posterior band is located at 12 o'clock position with the angle between its posterior limit and vertical orientation of the condyle doesn't exceed 10o."

"TMJ dysfunction is characterised by pain, clicking and functional restriction."
"Internal derangement also occurs secondary to abnormal disc morphology. Normally, the disc should be biconcave. Abnormal shapes include rounded, flattened, crumpled and perforated discs."
"On mouth opening, there may be recapture/relocation/reduction of the disc to a normal position - or it may recapture in one plane but not another. Alternatively, it may remain displaced. There is a strong association between failure of recapture of an anteriorly displaced disc and symptoms 9."
