Application of real time contrast-enhanced ultrasound in differential diagnosis of liver malignancies.

OBJECTIVE: To evaluate the value of real time contrast-enhanced ultrasound in differential diagnosis of malignant liver tumors.

METHODS: 60 patients pathologically diagnosed with liver cancer from May 2016 to May 2017 were selected as the objects. All patients received ultrasonic diagnosis followed by the observation on dynamic contrast enhancement of the image and the analysis on perfusion characteristics and difference in contrast-enhanced ultrasound results in patients with different types of liver cancer.

RESULTS: The relative height of artery of 21 patients with well differentiated hepatocellular carcinoma increased, including 12 cases of slow withdrawal of portal vein phase; The relative height of artery of 30 patients with middle-low differentiation of hepatocellular carcinoma increased along with rapid withdrawal of portal venous phase; In 9 patients with intrahepatic bile duct cancer, the artery was slightly higher to the periphery and low enhancement was found in the portal venous phase. There were some differences in the time and intensity of the patients with three different types diseases (P<0.05).

CONCLUSION: there are obvious differences in real time contrast-enhanced ultrasound features of patients with different types of liver malignant tumor which may provide references for clinical diagnosis.
