Locations, such as computer assisted detection marks, are presented in medical imaging diagnosis, such as for colon computed tomography diagnosis. To avoid fly-through and/or to assist in more rapid and thorough review of CAD marks, a summary of a plurality of detected candidates is pre-computed and presented to the user in a single collection. For example, a single display or screen view includes a gallery of images for different candidates. These pre-computed images are displayed on the screen, allowing the user to quickly identify locations of interest and rule out other locations. The summary may be used for navigation outside the CAD context, such as presenting different portions of an organ to be viewed.
