Figure 1
DICE similarity coefficients obtained with and without the proposed motion correction approach in pre (5-3 scheme) and post contrast (4-3-2 scheme) T 1 w image series. Average DICE coefficients over each T1w image series (left column), and over each individual T1-weighted image (right column) are shown. Similar DICE coefficients were observed before and after motion correction in T1w image series with high pre-registration coefficients (~0.9). Substantial improvements in DICE coefficient values were achieved in T1w image series with low pre-registration coefficients (< 0.9).
