BFPTT and BFT, respectively, represent blood flow (BF) of peritumoral tissue (PTT) and pancreatic tumor (T) as determined by perfusion CT. AUCPTT and AUCT, respectively, represent area under curve (AUC) with bolus injection of contrast media for PTT and T. Measurement results (average ± SD) appear at bottom of each column.
