Figure 7

Bar charts. Showing the coefficient of variation of left ventricular myocardial activity distribution in the healthy rats as a function of injection dose. Upper left: the chart with the standard (STD) pinhole collimator without post-reconstruction filter. Upper middle: the chart with STD with Gaussian filter of 1.5-mm kernel size (G1.5 mm). Upper right: the chart with STD with Gaussian filter of 2.5-mm kernel size (G2.5 mm). Lower left: the chart with the high-sensitivity (HS) pinhole collimator without post-reconstruction filter. Lower left: the chart with the STD with post-reconstruction filter. Lower right: the chart with the HS with post-reconstruction filter. The P value shown is based on Kruskal-Wallis test. Error bar indicates standard deviation. * indicates P < 0.05 between STD and HS graphs; **P < 0.05 among no filter, G1.5 and G2.5 mm graphs; and ***P < 0.05 between STD and HS graphs using all the 24 rats as a whole.
