JERUSALEM (Aug. 2)
A new procedure for pinpointing the locations of brain tumors, developed jointly by the Weizmann Institute and the Israel Atomic Energy Commission, was announced today.
The new method involves the use of fluorine-18 isotope. It is claimed to be more safe and more sure than methods used in the United States and Europe involving radioactive arsenic or copper tracers.
Officials said that because the fluorine tracer can be taken orally, instead of by injection, and also because it has a shorter life span than arsenic, a patient can undergo several checkups within a short period without substantial radiation dangers.
