Clinical value of contrast-enhanced ultrasound in early diagnosis of liver cirrhosis complicated with small hepatocellular carcinoma

Abstract

Objective To investigate the clinical value of contrast-enhanced ultrasonography in early diagnosis of liver cirrhosis and small hepatocellular carcinoma. Methods 60 patients with cirrhosis and small hepatocellular carcinoma were diagnosed by pathological examination.The number of lesions in the liver, the mode of enhanced expression were recorded, and all lesions were evaluated as benign and malignant before and after contrast-enhanced ultrasound. Results A total of 60 patients with 70 lesions were detected, all of which were less than 3cm.50 low differentiated carcinoma lesions, accounted for 71.42%, the contrast mode performance for arterial phase rapid enhancement, parenchymal lesion signal was lower than that of normal liver parenchyma, fast forward and fast.14 well differentiated carcinoma lesions, accounted for 20.00%, contrast mode performance for the arterial phase rapid enhancement, parenchymal lesion signal higher than that of normal liver parenchyma, namely fast and slow.Compared with before the contrast, the malignant grade of the lesion was significantly increased (χ2=4.525, P<0.05). Conclusion Ultrasound contrast in the early detection of liver cirrhosis with small liver cancer has high sensitivity, it is helpful to find lesions, evaluate the benign and malignant lesion, it can be used as a imaging method in diagnosis of small hepatocellular carcinoma.
