Analysis of the differential diagnosis and diagnostic efficacy of contrast-enhanced ultrasound combined with B-ultrasound in benign and malignant liver lesions
Objective To investigate the differential and diagnostic efficacy of contrast-enhanced ultrasound(CEUS)combined with B-ultrasound in benign and malignant liver lesions.Methods The clinical data of 60 patients with liver lesions admitted to the Affiliated Hospital of Xuzhou Medical University from December 2019 to December 2023 were retrospectively analyzed.All patients underwent B-ultrasound and contrast-enhanced ultrasound,and divided into liver cancer group and benign lesion group based on pathological examination results as the gold standard,to compare the ultrasonic signs of benign and malignant lesions and the effect of contrast-enhanced ultrasound combined with B-ultrasound in the diagnosis of liver cancer.Results The peak intensity of liver cancer group was higher than that of benign lesion group,the arrival time of contrast agent,peak time and fitting curve sharpness were lower than those of benign lesion group,the difference was statistically significant(P<0.05).In the benign lesion group,28 cases had regular shape,26 cases had clear boundary and 25 cases had low internal echo.In the liver cancer group,2 cases had regular shape,3 cases had clear boundary,and 6 cases had low internal echo,and the ultrasonic signs of the two groups were statistically significant(P<0.05).The accuracy,sensitivity and specificity of CEUS combined with B-ultrasound in the diagnosis of liver cancer were 93.33%,92.86%and 93.75%respectively,which were higher than those of the two single examinations,and the difference between the combination and B-ultrasound was significant(P<0.05).Conclusion Contrast-enhanced ultrasound combined with B-ultrasound can effectively distinguish benign and malignant liver lesions,and can improve the diagnostic efficiency of liver cancer compared with single B-ultrasound.
