Summary
DW-MR images and their corresponding apparent diffusion coefficient (ADC) maps provide unique information that reflects tissue cellularity and organization. The b-value images and ADC maps can be assessed qualitatively, and by comparing the varying signal intensities and appearances of tissues on these images, it is possible to characterize tissues and diseases. However, the ADC maps can also provide quantitative measurements of tissue water diffusivity, which can be used not only for disease assessment, but also for the evaluation of disease response to treatment. In order to achieve optimal image interpretation, the DW-MR images and ADC maps should be displayed with conventional morphologic images to enable the best assessment to be made. A pragmatic approach to utilizing DW-MR images and ADC maps for disease assessment is discussed in this chapter.
