Functional imaging methodology: recent clinical and research applications

The four applications of functional mapping, which are ongoing projects at the National Institutes of Health, demonstrate the clinical and research usefulness of this form of computerized image processing. Functional imaging not only yields an efficient reduction of large amounts of quantitative data, but also provides a visual presentation in which abnormalities can be easily appreciated. The examples presented illustrate several different approaches to the regional quantitative assessment of physiologic function, producing valuable clinical information in a manner which is not conveniently available by more conventional techniques
