Quantitative PET/MRI Parameters Investigated for Breast Cancer

PET Parameters
	SUVmax	Maximum standardized uptake value
	SUVmean	Average standardized uptake value
	SUVpeak	Peak standardized uptake value determined using 1 cm3 volume sphere including the most intense uptake
	MTV	Metabolic tumor volume
	TLG	Total lesion glycolysis = MTV × SUVmean
MRI Parameters
Pharmacokinetic modeling of gadolinium-based contrast agents	Ktrans	Volume transfer constant between the extravascular extracellular space and plasma
	ve	Volume of extravascular extracellular space per unit volume of tissue
	Kep	Flux rate constant between the extravascular extracellular space and plasma = Ktrans / ve
Diffusion weighted imaging	ADCmean	Mean apparent diffusion coefficient
	ADCmin	Minimum apparent diffusion coefficient
