Summary of quantitative MR imaging interpretation

	Quantitative Images
T2 map	Decay of MR signal from altered environmental water binding	Increased inflammation: T2 relaxation time prolonged Increased fatty infiltration: T2 relaxation time prolonged
Dixon	Fat quantification using in-phase and opposed-phase imaging	Increased fatty infiltration; increased fat fraction (fat/fat 1 water)
DW imaging	Random motion of water molecule	Increased cellularity in neoplasm: ADC value decreased Increased inflammation: ADC value increased Increased fatty infiltration: ADC value decreased
DT imaging	Muscle fiber tracking	Increased muscle injury: FA value decreased Increased muscle injury: MD increased
MR elastography	Mechanical properties measuring shear stiffness	Increased stiffness with increased disease
MR spectroscopy	Chemical information	Increased fatty infiltration; Increased lipid peak

Abbreviations: ADC, apparent diffusion coefficient; FA, fractional anisotropy; MD, mean diffusivity.
