Diffusion-Weighted Imaging in Head and Neck Cancer Technique, Limitations, and Applications

Diffusion-weighted imaging (DWI) of the head and neck represents a distinct method of MR imaging with far-ranging applications. Research continues to hone the capabilities of DWI in characterization, prediction, monitoring, assessing response to treatment, and detecting posttreatment changes and recurrent tumors. Pretreatment apparent diffusion coefficient (ADC) values can suggest the likelihood of response to treatment. DWI-obtained ADC values …
