Application value of SonoVue enhanced grey scale ultrasonography in diagnosis of gallbladder cancer

Objective To explore the application value of low-mechanical index enhanced grey scale ultrasonography in diagnosis of gallbladder cancer.Methods Thirty-two patients with gallbladder cancer confirmed by surgery and pathology were enrolled in this study.Their appearances of contrast enhanced ultrasound were analyzed retrospectively.The time of initial enhancement,peak enhancement,and initial decrease were observed,and enhancement appearances of lesion were compared.Results Thirty-two cases of gallbladder cancer were diagnosed by contrast enhanced ultrasound,30 cases of them were confirmed by surgery and pathology,2 cases were benign,the diagnose accordance rate was 93.8%.The common characteristics of gallbladder cancer were:focus and gallbladder wall were enhanced at the same time,hepatic artery phase was mainly highly enhanced,hepatic portal vein phase was mainly lowly enhanced,liver parenchyma phase was lowly or not enhanced.Conclusion Enhanced grey scale ultrasonography has characteristics in diagnosis of gallbladder cancer,which can improve the diagnose accordance rate of gallbladder cancer,it has good prospect in differential diagnosis of this disease.
