Furthermore, correlation between the mean value of target\/non\-target and overexpressed type of receptor of GEP\-NET was investigated \(TCS\/TCB versus type of SST receptor\). The highest correlation was obtained for TCS\/TCB ratio vs 2A and 2B type of receptor. The lowest correlation was obtained for the SST receptor type 1. Conclusions\: In the analysis of SPECT images of the receptor scintigraphy with the use of labeled somatostatin analogs in patient with GEP\-NET it is important to define the particular parameters of the methods of reconstruction to achieve optimized assessment of the SRS study. The choice of reconstructions parameters significantly influence on the quality of SPECT images and the quantitative assessment of target\/non\-target ratio. OSEM\(8,i\) is the most effectively setting of reconstructions parameters of OSEM Flash 3D™ algorithm. OSEM\(8,10\) setting gives the highest results in the qualitative assessment of SRS study. Application of scatter correction \(SC\) slightly improves quality of image in the visible assessment of the lesions and increases the value of target\/non\-target ratio. Using Gauss post\-filtering slightly degrade contrast with still high quality of images. But this result is possible if Gauss filter’s coefficient is not exceed d"]
