PCI and ACI of PVE. Both PCI and ACI were performed at 30 min after the CO2 microbubbles injection. Note the embolized portal vein with CO2 microbubbles was more visibly revealed by PCI (a) than ACI (b). The images were obtained at an energy of 19 keV, the pixel size was 3.25 µm × 3.25 µm, the exposure time was 1 s and the SDDs were 1 cm and 30 cm for ACI and PCI, respectively. |
