Özet
Magnetic resonance imaging (MRI) is a noninvasive imaging modality of the temporomandibular joint (TMJ). MRI provides a direct form of soft tissue visualization with excellent spatial and contrast resolution on sagittal and coronal MR images and essential information about position, morphology, and signal intensity characteristics of the TMJ structures. In TMJ evaluation most commonly used sequences are spin echo including T1, T2, and proton density (PD)-weighted images. While T1W images best demonstrate the joint anatomy, T2W images well depict both fluid and inflammatory changes with high signal intensity due to the increase in mobile protons resulting in a longer T2. Disc displacements, abnormal morphology of the disc, joint effusion and osteoarthritis, as well as the incidental findings around the TMJ region may be evaluated with MR images without using ionizing radiation.
