Viewing Comparison Studies

You can easily view next and previous comparison studies in the Viewer based on how you have defined the Auto Compare rules in User Settings.

  • If Auto Compare is enabled, the Viewer automatically displays up to six comparison studies when it initially opens. The number of studies that displays is determined by the selection made from the Maximum comparison studies to show list.
  • If Auto Compare is not enabled, the Viewer only displays the current study.

All modifications to series in the current study (for example, stack position, window/level, and presets) persist when you advance through priors using the Next Group of Comparisons command. For MG studies, zoom and pan also persist, and persist for priors when you scroll through the All Priors stack. Synapse excludes AR studies from this behavior.

Note:

To equalize the number of images as you scroll when prior studies have differing number of images, Synapse synchronizes the images by using the last image displayed multiple times.
