MAGNETIC RESONANCE TOMOGRAPHIC DIAGNOSTIC TECHNIQUE OF ARTICULAR DISK OF TEMPOROMANDIBULAR JOINT

摘要

FIELD: medicine.;SUBSTANCE: method involves performing the magnetic resonance tomography of the right and left temporomandibular joint with the use of a standard coil for the cerebral examination at the magnetic field intensity of 3 T with the closed and wide open mouth. The joint is additionally examined with the sub-open mouth having the lower jaw dropped, but not put forward. The closed-mouth MRT is performed in an oblique sagittal and oblique frontal projection. The MRT is performed in a sagittal projection, if the mouth is opened wide or sub-opened. In each projection in each position of the joint, magnetic resonance tomography is performed for 1 minute at a section thickness of 2 mm and the section clearance of 0 mm.;EFFECT: method provides the comfortable and accessible procedure ensured by no need for using a device for holding the mouth open and a special coil for the temporomandibular examination.;2 ex
