title: Advanced Imaging Techniques of the Skull Base.
abstract: Although conventional imaging can depict the anatomy of the head and neck with exquisite detail, it often falls short in its ability to characterize tissue physiology and abnormality; this is especially seen in the posttherapy setting where benign posttreatment changes and recurrent tumors can show intense postcontrast enhancement and similar features on conventional imaging. Advanced imaging can evaluate tissue physiology and, along with conventional imaging, provide a more accurate assessment of the skull base. This article describes the technical details and clinical applications of different advanced imaging techniques with a primary focus on diffusion-weighted imaging.
