Misalignment within DWI sequences due to eddy-current
based distortions in diffusion gradient images reduces
the accuracy of computed DWI and DTI parametric maps.
Our study in 21 breast cancer patients showed that
image-based distortion correction of DTI acquisitions
improves spatial alignment and lesion conspicuity and
may be essential for quantification of breast DTI
parameters beyond ADC.
