This monthâ€™s intriguing images come from radiation oncologist Ian Crocker and colleagues. Each one shows a patient with a glioblastoma, an aggressive brain tumor. The patientâ€™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 tumorâ€™s PET signal is more distinct than the tumorâ€™s appearance on MRI.
Since the 1990s, Mark Goodman, John Votaw and colleagues at Emoryâ€™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.
