Summary of selected studies on imaging approaches for distinguishing brain tumors from brain infections and abscesses

Technique	Main findings	References
MR spectroscopic imaging	Metabolite ratios and maximum choline/choline‐n, choline/creatine, and choline/N‐acetylaspartate ratios of the contrast‐enhancing rim could differentiate abscesses from GBM tumors (n = 15)	[53]
MRI	The apparent diffusion coefficient (ADC) MRI may differentiate GBM from brain fungal abscess in retrospective study (n = 90) as well as in MRI an investigation of 10 other patients	[54, 55]
MRI	The combination of DTI and dynamic susceptibility contrast perfusion‐weighted imaging improves the differentiation between tumors and brain infections

Abbreviations: DTI = diffusion tensor imaging; GBM = glioblastoma; MRI = magnetic resonance imaging.
