Figure 1

Imaging and infusion protocols and associated computed tomography (CT) calibration curves. Two infusions were performed: one bolus for perfusion measurements (40 mL at 4 mL/s) and one steady state for iodine biodistribution studies (160 mL at 0.5 mL/s). Volumetric scan (120 kVp, 375 mA, pitch=0.562, 2.5 mm thickness). Axial dynamic scan: slices centered on the tumor center for iodine time curves follow-up (80 kVp, 125 mA, 5 mm thickness). The enhanced attenuations (HU) versus iodine concentrations curves are represented on the right of the figure. The iodine concentrations rank from 0 to 12 mg/mL measured in a phantom at 80 and 120 kVp tube voltages. A cubic spline interpolation (at 80 kVp) and a linear fit (120 kVp) were used to retrieve intermediate concentrations. HU, Hounsfield units.
