New PET radiotracer could replace FDG for detecting Alzheimer’s

By Dan Krotz

UCLA researchers say they have developed a fluorine-based PET radiotracer that detects the neural plaques and tangles that signify the onset of Alzheimer’s disease. They believes the radioactive molecule could advance imaging’s role in both the early detection of Alzheimer’s and in the development of several drugs.

PET explores the mind of a math prodigy

By Dan Krotz

Rudiger Gamm can calculate 53 to the ninth power. In his head. He can also divide 31 by 61, and calculate the answer to 60 decimal points. The 26-year-old German prodigy’s talent attracted the curiosity of French and Belgian researchers who imaged his brain with PET while he performed math problems.

MR perfusion helps diagnose brain lesions

By Eric Barnes

In traditional MRI, both cerebral abscesses and high-grade tumors can be depicted as rim-enhancing lesions, rendering them indistinguishable. But researchers at Duke University say MR perfusion imaging can tell the two apart, based on tumors' increased vascularity.
