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 9

Interleaved symbol plots comparing the measured defect size expressed as percentage of left ventricular myocardium (%LV). With low (25 MBq) (left) or high (200 MBq) (right) injection dose between the healthy and myocardial infarct rats. Error bar indicates standard deviation; STD, the standard pinhole collimator; HS, the high-sensitivity pinhole collimator; G1.5 mm, Gaussian filter of 1.5-mm kernel size; G2.5 mm, Gaussian filter of 2.5-mm kernel size. *P < 0.05 by Wilcoxon test.
