Small volume correction

WebJan 22, 2004 · A region-of-interest (ROI) analysis with small volume (SV) correction was therefore carried out; this used specific movement activations (e.g., for finger movements) as the ROI of the respective word categories (e.g., arm-related words). Small-volume analysis was carried out for both hemispheres separately. For smaller volumes, W96 shows that the correction must take into account the geometric properties of the volume, such as shape and surface area. This is important, because you may well have an apriori hypothesis as to an area of expected activation in a statistical parametric map.
