Biexponential analysis of diffusion-weighted imaging: comparison of three different calculation methods in transplanted kidneys

BackgroundBiexponential analysis has been used increasingly to obtain contributions of both diffusion and microperfusion to the signal decay in diffusion-weighted imaging DWI of different parts of the body. PurposeTo compare biexponential diffusion parameters of transplanted kidneys obtained with three different calculation methods. Material and MethodsDWI was acquired in 15 renal allograft recipients (eight men, seven women; mean age, 52.4 ±...
