Separate single-tracer scans were acquired using the multi-tracer dynamic scanning protocol (top). The raw data from each scan were then combined to emulate rapid multi-tracer scans (triple-tracer shown at bottom), providing exactly paired single- and multi-tracer components permitting direct evaluation of the accuracy of the multi-tracer signal separation procedure. In practice, separate single-tracer scans would require 5 hr 10 min or longer to complete in order to wait for decay of one tracer before imaging the next, whereas the rapid triple-tracer procedure can be completed in the time required for a single FDG scan alone.
