Following some time at a clinical site recently, I noticed the knowledge and understanding required by practitioners in order to create fused image data sets in SPECT/CT and PET/CT. Having the correct amount of CT and PET or SPECT data can really highlight the presence of disease.
Image reviewing can be a subjective aspect of nuclear medicine and knowing how much "blending" is required comes from experience and an understanding of the modalities. This is particularly an issue when selective data sets are sent to PACS for reviewing by consultants.
The advent of "floating" licences has made it slightly easier to view fused hybrid data sets on remote systems, where the user has full access to imaging blending tools.
