Abstract

Functional MRI studies of human brain require rapid data acquisition techniques, to map dynamic changes with sufficient anatomical coverage. In addition, task activation studies employing functional MRI require a high scan sensitivity, in order to discriminate the small, activation-related signal changes from background noise. An overview is given of current fast scan methods, which are sensitized to detect susceptibility changes related to task-induced changes in blood oxygenation. Sources of artifacts are discussed, as well as their effect on image quality.
