Figure 3. Measuring Blood Pool Activity in the Brachiocephalic vein and the Right Atrium.

Figure 3

Regions of interest for measuring blood pool activity in the brachiocephalic vein (top) and right atrium (bottom) are shown in the en-face of the valve (left) and coronal (right) planes. Note that the right atrium is a much larger structure allowing for larger regions of interest with less potential for partial volume artifact problems related to poor registration. Tukey plot demonstrates mean SUV values for 5 contiguous slices from brachiocephalic (blue) and 2 from the right atrium (purple). Note the variation in brachocephalic vein measurements between those taken most caudally versus those taken most cranially.
