Fig. 8. —Bar graph shows average tumor-to-liver contrast during each of three imaging passes for both patients with cirrhosis (n = 16) (white bars) and patients without cirrhosis (n = 9) (black bars). For both patient groups, maximum tumor-to-liver contrast occurred during second pass—that is, during late arterial or portal venous inflow phase. Difference in tumor-to-liver contrast between second pass and first and third imaging passes was determined using Student's t test and was significant for both patient groups (cirrhotic patients, p < 0.001; noncirrhotic patients, p < 0.006).
