Value of Magnetic Resonance Diffusion Weighted Imaging Examination in Differentiate Diagnosis of Hepatocellular Carcinoma and Hepatic Hemangioma
Objective:To explore the value of magnetic resonance diffusion weighted imaging(DWI)examination in differentiate diagnosis of hepatocellular carcinoma and hepatic hemangioma.Method:The clinical data of 89 patients with liver tumor admitted to Kweichow Moutai Hospital from August 2020 to August 2022 were retrospectively analyzed.All patients underwent routine magnetic resonance imaging(MRI)plain scan and magnetic resonance DWI examination.Taking the postoperative pathology as the gold standard,detection situation of hepatocellular carcinoma and hepatic hemangioma by routine MRI plain scan and magnetic resonance DWI examination were counted.The value of routine MRI plain scan and magnetic resonance DWI examination in the differentiate diagnosis of hepatocellular carcinoma and hepatic hemangioma was analyzed.The consistency of routine MRI plain scan and magnetic resonance DWI examination with postoperative pathology was analyzed.The average apparent diffusion coefficient(ADC)values of different b values in patients with hepatocellular carcinoma and hepatic hemangioma were compared.Result:Among the 89 patients with liver tumor,34 cases of hepatocellular carcinoma and 55 cases of hepatic hemangioma were detected by postoperative pathology.Routine MRI plain scan showed 29 cases of hepatocellular carcinoma and 60 cases of hepatic hemangioma.Magnetic resonance DWI examination showed 33 cases of hepatocellular carcinoma and 56 cases of hepatic hemangioma.The sensitivity and accuracy of magnetic resonance DWI examination were higher than those of routine MRI plain scan,and the differences were statistically significant(P<0.05).Kappa test showed that routine MRI plain scan was acceptable consistent with postoperative pathology(Kappa=0.731,P<0.001).There was good consistency between magnetic resonance DWI examination and postoperative pathology(Kappa=0.928,P<0.001).The average ADC values of 50 s/mm2,400 s/mm2,1 000 s/mm2 in patients with hepatocellular carcinoma were lower than those in patients with hepatic hemangioma,and the differences were statistically significant(P<0.05).Conclusion:Magnetic resonance DWI examination is more valuable in the differential diagnosis of hepatocellular carcinoma and hepatic hemangioma,which can improve the sensitivity and accuracy of disease diagnosis,reduce the occurrence of missed diagnosis and misdiagnosis,so as to better guide the clinical treatment.
