The value of MRI-enhanced sequence hepatobiliary-specific phase morphology and quantitative parameters in predicting postoperative recurrence of hepatocellular carcinoma
Objective To analyze the value of morphological signs and quantitative parameters in the hepatobiliary-specific phase of MRI-enhanced sequences in the prediction of postoperative recurrence of hepatocellular carcinoma(HCC).Methods Seventy-six HCC patients admitted from September 2020 to September 2023 were selected,and all enrolled patients underwent MRI examination to analyze the value of MRI enhancement scanning in predicting postoperative recurrence of hepatocellular carcinoma.Results Twenty-five cases of 76 patients had postoperative recurrence and 51 cases had no recurrence in the follow-up.Seventy-four cases(97％)of the patients showed low signal in hepatobiliary specific phase,and 2 cases(3％)showed equal or high signal;46 cases(39％)had regular tumor boundaries,and 30 cases(61％)had irregular ones;12 cases(16％)had paraneoplastic low signal,and the remaining 64 cases(84％)were not observed paraneoplastic low signal;The enhanced RIR and CER levels were lower in the high-grade group than in the low-grade group(P＜0.05).The enhanced RIR and CER levels were lower in the recurrent group than in the non-recurrent group(P＜0.05).The recurrence rate of 9％(4/46)in the group with regular tumor borders was lower than that of 30％(9/30)in the group with irregular tumor borders(P＜0.05);and the recurrence rate of 7％(3/42)in the high-CER group was lower than that of 29％(10/34)in the low-CER group(P＜0.05).Multifactorial Cox regression analysis showed that CER and tumor border irregularity were independent risk factors for postoperative recurrence of hepatocellular carcinoma(P＜0.05).Conclusion The morphological signs and quantitative parameters of hepatobiliary specific phase of MRI enhancement sequences in the prediction of postoperative recurrence of hepatocellular carcinoma have high application value and can guide clinical diagnosis and treatment.
