- W3028993710 abstract "Objective To investigate the enhancement features of hepatic tumors between dynamic three-dimensional contrast-enhanced ultrasonography (3D-CEUS) and two-dimensional contrast-enhanced ultrasonography (2D-CEUS).Methods Totally,65 patients with 67 focal liver lesions were examined with 2D-CEUS and dynamic 3D-CEUS.Enhancement patterns,sharpness or three-dimensional effect in different phases,definition of blood vessel in arterial phase and spatial relationships of tumor and vascularity of different hepatic tumors on the two imaging modes were compared statistically,the value of two modes in differential diagnosis of hepatic tumors was also evaluated.Results Dynamic 3D-CEUS was similar to 2DCEUS with respect to enhancement patterns,sharpness or three-dimensional effect of tumor in arterial and portal phases( P ＞0.05).And there was no significant difference between the value of dynamic 3D-CEUS and 2D-CEUS in differential diagnosis of hepatic tumors:the sensitivity,specificity,positive predictive value and negative predictive value were 98.0％,81.3 ％,94.3 ％ and 92.9％ for 3D-CEUS,and were 96.1％,81.3％,94.2％ and 86.7％ for 2D-CEUS,respectively.However,3D-CEUS was superior to 2D-CEUS in the display of definition of blood vessel in arterial phase,and spatial relationships of hepatic tumor and vascularity( P ＜0.05).Conclusions Dynamic 3D-CEUS is a useful technique in the differential diagnosis of hepatic tumors as well as 2D-CEUS,and dynamic 3D-CEUS displays the spatial relationship of hepatic tumors and vascularity more visually and effectively,which provides additional information in the diagnosis and therapy of hepatic tumors.Key words: Ultrasonography,three dimensional; Microbubbles; Liver neoplasms" @default.
