CPT^® 70336, Under Diagnostic Radiology (Diagnostic Imaging) Procedures of the Head and Neck

Magnetic resonance imaging (MRI) is a noninvasive medical test that helps physicians diagnose and treat medical conditions .MR imaging uses a magnetic field, radio frequency pulses and uses the natural magnetic properties of the hydrogen atoms in our body that emit radiofrequency signals when exposed to radio waves in an electro–magnetic field. A computer produces detailed 3D tomographic pictures of soft tissues and all other internal body structures. MRI does not use ionizing radiation (X–rays).Magnetic resonance imaging (MRI) is the primary modality for the evaluation of the temporomandibular joint (TMJ). MRI provides sharp tissue contrast for visualizing the soft tissue and periarticular structures of the TMJ and study intra–articular abnormalities with the use of dedicated coils and high spatial resolution. Dynamic maneuvers (opening and closing the mouth) are necessary part of the examination.
