Anatomical study of human temporo-mandibular joint by magnetic resonance

Nuclear Magnetic Resonance (NMR) is a technique able to create high quality images with huge tissutal characterization and oriented on all the spatial plans chosen by the operator with no exposition to ionizing radiations therefore with no biological risk at all. NMR has become the "gold standard" method for the study of the temporo-mandibular joint (TMJ). We studied the normal anatomy of the TMJ for its relevance in the study and understanding of pathological situations. High field NMR devices (1,5 Tesla) allow to reveal the precise anatomical details of human joints; images obtained by this kind of NMR can be compared to images obtained by means of other devices currently used in clinical practice. Although the remarkable technological progresses of the diagnostic methods based on ionizing radiations, the NMR is considered the most consistent technique for the morphological and functional investigation of the TMJ for the use of different spatial plans and for its high contrast resolution (expecially for devices with high field -minimal 1,5T-). NMR device of 1,5 Tesla perfectly characterized the articular structures (bones and ligaments), the articular disk and the bone marrow.
