The PET scan tags glucose with a radioactive marker and it shows areas of concentration where metabolism is high (fast cell growth) when scanned.

RECAF is the receptor for AFP that is a marker for cancer. Radioactive AFP is injected and concentrates in areas with receptors and shows the location of cancer when scanned.

As far as one being better than the other, RECAF has been shown to detect very early cancers. The ability to detect in either case would also vary if the cancer is fast or slow growing. If the PET scan was fantastic, I don't think ABT would be looking at RECAF.
