This is movie tracing the delivery and distribution of a radiolabeled sugar (fluorodeoxyglucose) following injection into a leg vein, captured in real time by the EXPLORER scanner. In the first few seconds following injection it travels to the heart from where it is distributed through the arteries to all the organs of the body. At around 3 minutes, some of the substance is excreted from the kidneys into the bladder. Gradual accumulation of the glucose can be seen in the heart, brain and liver over time. The EXPLORER scanner will allow the delivery, metabolism and excretion of many substances and drugs to be followed in the entire human body in a similar manner.
