The Internal derangement of temporomandibular joint disc was evaluated by using
magnetic resonance imaging and arthrogram in 5 patients having reciprocal clicking or
locking and in 5 normal subjects.
Parasagittal multisections on both closed and open mouth were serially obtained by
using a 1.5 Tesla MR system and surface coil pith CSMEMP, MPGR. MR images
obtained were analized by correlating with images of arthrograms.
The obtained results were as follows :
1. Displaced meniscus was clearly delineated as dark structure on MR images other
than on arthrograms of closed mouth view of patient having clicking or locking.
2. The deltoid white images of synovial fluid were identified in the glenoid fossa and
on the posterior surface of condyle on open mouth view and partly depicted on closed
mouth view, of parasagittal sections by MPGR.
3. The greyish image of joint fluid was identified on the posterior surface of condyle
on the open mouth view of parasagittal sections by CSMEMP.
4. The structural relationship among condyle, meniscus, and fluid showed the variety
of images owl each parasagittal view.
