Imaging response predictors following drug eluting beads chemoembolization in the neoadjuvant liver transplant treatment of hepatocellular carcinoma

Figure 3 Calculation method for individualization of the dose of the chemoembolic agent received by treated hepatocellular carcinoma in situations of impossibility of the superselective catheterism. A: Magnetic resonance imaging pre-chemoembolization abdomen - post-contrast T1 weighted phase - showing three confluent hypervascular lesions; B: Selective hepatic arteriography in segment VI of the right hepatic artery showing hypervascular lesions characteristic of hepatocellular carcinoma; C: Intraoperative cone beam tomography with selective arterial contrast in segment VI - venous phase - showing three confluent lesions with contrast medium lavage; D: Diameter of hepatocellular carcinomas located in segment VI to be treated; E: Exemplification of the calculation of dose individualization of the chemoembolic agent administered; F: Equation of individualized chemoembolic dose. MRI: Magnetic resonance imaging.
