Figures
- Fig 1.
3D volume rendering beginning 15 seconds after the start of injection (A) with and (B) without cranial bones. C, Shown 7 seconds after the start of injection. D, Slightly enhanced visualization of the superior sagittal sinus and inferior sagittal sinus (arrow) increasing gradually from 12 seconds after the start of injection. E, Optimum visualization of the superior sagittal sinus and inferior sagittal sinus 16 seconds after the start of injection. F, Decrease in enhancement of the superior sagittal sinus at 25 seconds after the start of injection. 1, dorsal cerebral veins; 2, carotid artery; 3, transverse facial artery; 4, sagittal venous sinus; 5, lingual artery; 6, caudal auricular artery; 7, infraorbital artery; 8, ophthalmic venous sinus; 9, supraorbital vein.

Results for a healthy domestic pig (pig 1). A, Nonenhanced sagittal image with a 6-mm section thickness. B, CTA in the sagittal plane at 14 seconds after the start of contrast injection. Various color ramps, selected according to user preference, were used to display the sagittal perfusion CT maps of (C) CBF, (D) CBV, and (E) MTT. These perfusion CT maps show enhancement of the lingual artery and vein in addition to the brain.
- Fig 3.
Results for a healthy domestic pig (pig 2). A, Nonenhanced sagittal image with a 6-mm section thickness. B, Oblique image at a 40° angle to the horizontal line shown in Fig 2A. C, CTA in an oblique plane at 14 seconds after the start of contrast injection. D, CBF. E, CBV. F, MTT.
