TMJ Magnetic Resonance: Technical Considerations
Imaging of the temporomandibular joint (TMJ) has been continuously evolving along with the advancement of imaging technologies. Even though many imaging modalities are currently used to evaluate the TMJ (i.e., cone beam computed tomography—CBCT—and multi-detector computed tomography—MDCT), the use of magnetic resonance imaging has increased due to its great contrast resolution, its strength in highlighting soft tissue structures and signs of inflammation, and its capability in acquiring dynamic imaging for demonstration of the functionality of the joint (Bag et al. 2014). Furthermore, MRI does not involve ionizing radiations and this helps in limiting the overall history of patient exposure (Niraj et al. 2016). On the other hand, the relative disadvantages of MRI compared to CT include a more complex scanning technique and a longer acquisition time. The advantages of CT over MRI are enhanced bone details and 3D assessment of congenital, developmental, and traumatic conditions (Bag et al. 2014; Niraj et al. 2016). In this chapter, the reader will be given the essential and basic information to understand the principles of physics that underlie the creation of MR images.
