Kaplan-Meijer survival curves in patients with high (green) vs. low (blue) AMT uptake ratios (based on the cutoff threshold of 1.94 tumor/cortex SUV ratio, determined by an ROC analysis based on 1-year survival). Patients with above-threshold ratios had a substantially longer cumulative survival (hazard ratio: 30.2 [95% CI: 3.5–259]; P=.002).
