Abstract
Objective
This study examined the use of positron emission tomography (PET) ratios to improve
the diagnostic ability of 18F-FDG PET/computed tomography (CT) in the differentiation
of enhancing brain metastases, central nervous system lymphomas, and gliomas.
Materials and methods
Seventy-six patients with malignant brain tumors and available magnetic resonance
imaging and PET/CT examinations were included.
Results
Among standardized uptake value (SUV)-related parameters tested, tumor maximum SUV
to ipsilateral cortex maximum SUV ratio (Tmax:WMimax) and maximum SUV (SUVmax) proved
to be the two most valuable parameters for differential diagnosis.
Conclusion
In addition to SUVmax, Tmax:WMimax also seems to provide helpful information for the
differential diagnosis of lymphomas from other malignant brain tumors.
