Motion during breast MR examination can degrade DCE data
and cause spatial mismatches between sequences. Data
acquired from 19 patients was retrospectively corrected
using rigid and non-rigid schemes. For the DCE series,
mean coefficients of variation were found to be
45.23.9%, 40.03.1% and 35.72.5% for the original
data, rigid motion corrected data and the non-rigid
motion corrected data. Non-rigid registration between MR
series was successfully applied to all patients and
showed good visual agreement. The global 4D registration
methodology enables researchers and clinicians to
contour single volume of interests that can be used to
simultaneously interrogate multiple breast MR series.
