That's the "after scientology/vitamin healing" scan.
That's a PET scan, where the patient is given marked radioactive glucose to reveal parts of the body which have a high metabolism. Since malignant tumors have a high metabolism, they would show up as black spots on that scan. But so will organs which also have a high glucose consumption, such as the brain and heart.
You can also see a bit of it in the kidneys, which is normal since they are involved in its excretion, and a little bit in the liver, which stocks sugar. The two dark spots below the brain are the thyroid, which often concentrates radioactive substances. The very dark spot down is the bladder filling up with the marker for excretion IMO.
Hey, thanks for that explanation. Very informative.
Could you explain what the other two pictures (CT scans?) are and what they show please?
