↵* P < 0.05.
↵† P < 0.001.
↵‡ Only 2 voxels in corresponding CSI; therefore, it was not possible to calculate correlation.
SUV_mean, SUV_max, and SUV_min = mean, maximum, and minimum standardized uptake values, respectively.
Slabs of tumor are through lesion at different levels. Table shows maximum SUV correlation (r) with corresponding P values for ¹³C-lactate and ratio of ¹³C-pyruvate to ¹³C-lactate.
