Digital image blurring filters are developed to examine contrast perception problems related to visual acuity (specifically, recognition acuity) loss.
It is very useful to examine contrast-enhanced chest CT images and to create a reconstructed three-dimensional CT image for safe surgery.
Standard staging for PCNSL needs to examine contrast-enhanced CT of the chest, abdomen, and pelvis and sometimes bone marrow biopsy to exclude systemic lymphoma [ 32].
In the future, there will be a need to develop statistical approaches to examine contrasting hypothesis concerning the existence of overlapping DAMs, including the change in function of the protein or the position where the overlapping DAMs are seen.
Using the final multivariable model, the investigators examined contrasts for independent variables with >2 categories.
Because sex × age and race × age interactions were present in those models for one or both time periods, we examined contrasts between the two time periods separately for each sex/age category and for each race/age category.
Another study examined contrast-response relationship using drifting gratings that could take 3 different orientations, and concluded that orientation tuning in the macaque is contrast-invariant [27]; however, orientation tuning curves were not formally examined at different contrasts.
