Figure 4b: — (a) Kaplan-Meier curves by using multiparametric approach. Blue curve = responders with both ADC and arterial enhancement (ADC ≥ 15% and enhancement ≥ 25%). Median survival was 41 months. Green curve = nonresponders with both ADC and arterial enhancement (ADC < 15% and enhancement < 25%). Median survival was 15.5 months. Red curve = patients who demonstrated either ADC or arterial enhancement response (ADC ≥ 15% or enhancement ≥ 25%). Median survival was 15 months (log-rank test, P < .003). (b) Kaplan-Meier curves by using multiparametric approach. Blue curve = responders with both ADC and venous enhancement (ADC ≥ 15% and enhancement ≥ 50%). Median survival was 49 months. Green curve = nonresponders with both ADC and venous enhancement (ADC < 15% and enhancement < 25%). Median survival was 15 months. Red curve = patients who demonstrated either ADC or venous enhancement response (ADC ≥ 15% or enhancement ≥ 25%). Median survival was 25 months (log-rank test, P < .003). Cum = cumulative.
