Images filtered for uniformity with PURE may contain residual signal variation arising from sources other than tissue contrast. Such variation can be more apparent in PURE filtered images than in unfiltered images, because default window width values display more contrast after PURE. Please refer to Filter considerations for more detail.

Images filtered for uniformity with SCENIC may contain hyper- or hypo-intense signal areas that are not apparent on unfiltered images. SCENIC filtering is derived from the image itself, and the results can therefore be affected by tissue shape and contrast.
