Fig. 1From: Assessment of mouse-specific pharmacokinetics in kidneys based on 131I activity measurements using micro-SPECTOverlays of SPECT and CT transverse (left) and longitudinal (right) section images of the physical phantom, filled with a [131I]-NaI solution (10.4 MBq mL−1). VOIs used for analysis are shown as an overlay in yellow (6 mm rod) and orange (4 mm rod) colours. A large air bubble is present inside the 6-mm-diameter rod, which limited the number of VOIs in that rod that could be used for analysisBack to article page
