PCT imaging with ICA reference of a patient with right tongue base squamous cell carcinoma. PCT imaging with ICA reference of a patient with right tongue base squamous cell carcinoma. A, Axial contrast-enhanced CT scan shows a mass involving the right tongue base. Regions of interest have been placed in the ICA (1), the internal jugular vein (2), and the tumor (3). B, Time-enhancement curve for the patient shown in A. The first peak is arterial enhancement; the second is venous (arrows). The flat curve at the bottom represents tissue region-of-interest (3) enhancement. C, Fractional tissue BF map for the patient in A. There is increased fractional tissue BF in the region of the mass lesion compared with surrounding tissue. D, PS map for the same patient. The tumor site displays increased capillary permeability compared with surrounding tissue. A.C. Miracle et al. AJNR Am J Neuroradiol 2009;30:1598-1601 ©2009 by American Society of Neuroradiology
