Value of DCE-MRI parameters and apparent diffusion coefficient in evaluating microvascular invasion of hepatocellular carcinoma
Objective:To evaluate the value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)parameters and apparent diffusion coefficient(ADC)values in microvascular invasion of hepatocellular carcinoma.Methods:85 patients with liver cancer who underwent surgical treatment from February 2021 to April 2023 were selected as the study objects.The ADC values were measured by DCE-MRI before operation.The results of microvascular invasion were analyzed and patients were divided into microvascular invasion positive group and microvascular invasion negative group.To analyze the value of DCE-MRI parameters and ADC values in evaluating microvascular invasion of hepatocellular carcinoma.Results:In 85 patients with liver cancer,the pathological diagnosis showed that 33 patients were positive for microvascular invasion,52 patients were negative.Ktrans,Kep and Ve values in positive microvascular invasion group were higher than those in negative group,and ADC values were lower than those in negative group(P<0.05).Receiver operating characteristic curve was drawn.The results showed that the parameters obtained by DCE-MRI scanning(Ktrans,Kep,Ve)and ADC values had certain value in evaluating microvascular invasion of liver cancer,and the area under the curve were all greater than 0.70,and the combined evaluation value was more ideal.Conclusion:Preoperative DCE-MRI parameters and ADC values can be used to evaluate microvascular invasion in patients with liver cancer.
