Abstract
|
|
|
For understanding of anatomy, physiology, and diseases of human TMJ, it is required to evaluate quantitatively the movement of the disc and condyle head of mandible. The histologic section of cadaver TMJ were examined, and the MR image and its
details
of anatomy were qualitatively evaluated.
In comparison of the histologic section of autopsy specimen with the MR image at the same section, it was enable to differentiate the shape of articular disc, anterior and posterior attachments and adjacent soft tissues, because of excellent
reproducibility of anatomical structure.
MRI with surface coils is a proven method for the assessment of internal derangements of the TMJ and is rapidly surpassing arthrography and CT as the imaging method of choice. The major advantage of MR in comparison to arthrography and CT are: 1)
it is
noninvasive; 2) it requires no ionizing radiation for image acquisition; 3) it permits a direct visualization of the disk and joint structures; and 4) multiplanar imaging is readily obtained and more easily interpretable.
