Abstract:Objective To explore the value of multislice spiral CT (MSCT) based on dynamic contrast enhancement and computer
post-processing in the differential diagnosis of regenerative nodule of type B liver cirrhosis and small hepatocellular carcinoma.
Methods The clinical data of 56 patients with regenerative nodule of type B liver cirrhosis (nodule group) and 55 patients with
small hepatocellular carcinoma (liver cancer group) confirmed by puncture or surgical pathology from June 2019 to October
2021 were retrospectively analyzed. The results of MSCT plain scan, arterial phase, portal vein phase, delayed phase enhanced
scan and computer post-processing were compared between the two groups. The sensitivity, specificity and accuracy of MSCT
based on three-phase dynamic enhancement and computer post-processing in the regenerative nodule of type B liver cirrhosis and
small hepatocellular carcinoma was analyzed. Kappa was used for consistency test. Results There was no significant difference
in gender, age and body mass index between the two groups (P>0.05). The sensitivity of MSCT based on dynamic enhancement
and computer post-processing to differentiate regenerative nodules of type B liver cirrhosis and small hepatocellular carcinoma
were 96.43% and 92.73% respectively, and the specificity were 92.73% and 96.43% respectively, and the accuracy were bath
94.59%. There was no significant difference in MSCT values between the two groups in the non scanning period and the delayed
period (P>0.05). The value of MSCT in portal vein phase in liver cancer group was lower than that in nodule group (P<0.05), and
the value of MSCT in arterial phase was higher than that in nodule group (P<0.05). Conclusion MSCT based on dynamic contrast and
computer post-processing has a good differential diagnostic value for regenerative nodule of type B liver cirrhosis and small hepatocellular
carcinoma, which can provide objective evidence for clinicians to determine the condition and formulate appropriate treatment options.
