High-contrast brain tumor imaging

This month’s intriguing images come from radiation oncologist Ian Crocker and colleagues. Each one shows a patient with a glioblastoma, an aggressive brain tumor. The patient’s brain was scanned in two ways: on the left, MRI (magnetic resonance imaging) and on the right, PET (positron emission tomography), using a probe developed at Emory. We can see that the tumor’s PET signal is more distinct than the tumor’s appearance on MRI.

Since the 1990s, Mark Goodman, John Votaw and colleagues at Emory’s Center for Systems Imaging have been developing the probe FACBC (fluoro-1-amino-3-cyclobutyl carboxylic acid) as a probe for the detection of tumors.
