FIGURE 1. Arrows show direction of changes in mean blood flow and Ki values before after chemotherapy. Ki decreased for all response groups. Blood flow decreased for mCR and PR groups; however, it increased for NR group. Error bars represent SEM.
FIGURE 3. Correlations between blood flow and Ki or K1 before and after chemotherapy excluding 1 far outlier. (A) Blood flow and Ki before chemotherapy. (B) Blood flow and Ki after chemotherapy. (C) Blood flow and K1 before chemotherapy. (D) Blood flow and K1 after chemotherapy. Correlation between blood flow and Ki improved after chemotherapy.
