Correlations between anatomic and MRI sections of human cadaver temporomandibular joints in the coronal and sagittal planes.

摘要: Cadaver material was used in this study to correlate sequential sagittal and coronal T1-weighted magnetic resonance images against anatomic detail. Magnetic imaging (MRI) found accurately represent soft tissues normal deranged joints. In contrast previous reports, MRI the discal-retrodiscal junction did not appear give false positive findings for disc displacement. Magentic provided good of bony outline, particularly views. Difficulties interpretation arose when different adjoining produced same MR image; central tendon lateral pterygoid muscle can as an extension disc, a distorted displaced disc. sections, medial hernia sac lower joint space seen constant indicator component displacement; however, evident images. Fibrocartilaginous remodeling articular surface projecting into discal perforation presented image tissue. Because discs are often thinned over pole, it is difficult determine whether tissue present between surfaces at its resolution. Subcortical bone spaces may be misinterpreted areas avascular necrosis osteochondritis dissecans. It recommended that sequence TMJ include mid-condyle lateral, central, images; most interpret.
