From: Impact of injection dose, post-reconstruction filtering, and collimator choice on image quality of myocardial perfusion SPECT using cadmium-zinc telluride detectors in the rat

Figure 2

Consecutive short-axis slices of myocardial perfusion SPECT with various injection doses (range: 25 to 200 MBq). In the healthy rats without post-reconstruction filtering (A), with Gaussian filter of 1.5-mm kernel size (B), and with that of 2.5-mm (C). Each rat was imaged twice; one with the standard (STD) pinhole collimator (left) and the other with the high-sensitivity (HS) pinhole collimator (right). However, different rats were presented at different doses.
