Longitudinal Evaluation of Fatty Acid Metabolism in Normal and Spontaneously Hypertensive Rat Hearts with Dynamic MicroSPECT Imaging

Figure 2

Dynamic cardiac 123I-BMIPP pinhole SPECT projection data acquired by one detector head during the interval 2–36 s for (a) a WKY normal rat and (b) an SHR. These early time frames show the arrival of the injected bolus at the heart, followed by initial uptake in the myocardium. The maximum numbers of counts in a detector bin are 10 and 12 for the WKY normal rat and SHR, respectively.
