Low contrast medium and radiation dose for hepatic computed tomography perfusion of rabbit VX2 tumor

Figure 3 Correlation and agreement of perfusion parameters for viable tumor component obtained using the 80 kVp protocol with iterative reconstruction (low radiation dose and concentration contrast medium) and 120 kVp protocol with filtered back projection (conventional radiation dose and concentration contrast medium). A: HAP; B: HPP; C: HBF; D: HPI; E: HAP-HAP; F: HPP-HPP; G: HBF-HBF; H: HPI-HPI. IR: Iterative reconstruction; HAP: Hepatic arterial perfusion; HPP: Hepatic portal perfusion; HBF: Hepatic blood flow; HPI: Hepatic perfusion index.
