Title: The Value of Diffusion Weighted Imaging in Identifying Cholangiocarcinoma
Abstract: Purpose To discuss the diagnosis study of diffusion weighted imaging(DWI)in identifying Cholangiocarcinoma and Liver space-occupying.Materials and Methods Diffusion-weighted MR imaging and measurement of apparent diffusion coefficient(ADC value)were performed in 50 healty volunteers,25 patients with cholangiocarcinoma and 59 patients with focal liver lesions.The research group cholangiocarcinoma including intrahepatic bile duct carcinoma and liver lobectomy,the other group including cases of hepatocellular carcinoma10,liver metastases 11,hepatic hemangioma 20,liver cyst 18.All patients at the same time to do multi-phase dynamic contrast-enhanced MRI,lesions by observing the phases of enhanced features,to further provide the basis for the qualitative diagnosis.Results Normal liver tissue ADC value was 1.56±0.23,cholangiocarcinoma,hepatocellular carcinoma and liver metastases of ADC values were 1.39±0.46,1.24±0.30,1.31±0.56,between the difference was not significant,Hepatic hemangioma,liver cyst ADC values are 1.81±0.44,3.34±0.87,or more malignant tumors were lower than the ADC value of benign lesions,that is,the ADC value of cholangiocarcinoma with hepatic benign lesions were statistically significant differences between.In dynamic contrast-enhanced scan,35.2% of liver cancer,80% and 36% of cholangiocarcinoma metastatic tumor lesions can be seen portal venous phase and delayed phase enhanced.Conclusions DWI and ADC value measurements is useful in differentiating cholangiocarcinoma and benign focal hepatic lesions,can be used as a liver,gall bladder organ MRI sequence supplementary examination.
