Abstract:
Objective To study the clinic imaging features and the clinic applications of the contrastenhanced ultrasound(CEUS) in the diagnosis of gallbladder carcinoma.Methods The characteristics of CEUS were reviewed in 24 patients with gallbladder carcinoma proven pathologically. Results After injection of SonoVue, all gallbladder carcinoma of 24 cases showed enhancement and these lesions looked clearer than those in conventional ultrasound.The analysis of time-intensity curve indicated the upslope of curve was steep in the lesions,which was flat in normal liver parenchyma around.In 10 cases of thick wall of gallbladder carcinoma, quick and obvious enhancement was seen in 9 cases, 1 case showed poor enhancement during scanning,but thick and tortile blood vessels could be seen in the thickening wall.Quick and uneven enhancement was been seen in both 8 cases of soft-tissue mass and 6 cases of nodules within gallbladder.Five cases of gallbladder carcinoma with liver metastasis revealed more liver metastasis depend on CEUS.Conclusions CEUS plays an important role in diagnosis and improving the diagnostic accuracy for gallbladder carcinoma.
