Abstract:
Objective To assess three-dimensional color Doppler energy (3D-CDE) in the diagnosis of liver tumors.Methods Vascular pattern of 2D- and 3D-CDE were used to analyze 106 tumors of 96 patients,and their sensitivity and specify were calculated respectively.Three-dimensional volumetric measurement was used to calculate the volume,vessel counts of tumor,as well as the ratio of vessel counts and volume,whereas vascular index (VI) of both benign and malignant lesions were assessed.Results ①Using the vascular pattern of IE as diagnosis standard of liver malignant,the sensitivity and specificity of 2D-CDE and 3D-CDE were 21.33%,100% and 81.33%,100%,respectively) using the vascular pattern of II and Ⅲ,the sensitivity and specificity were 73.33%,67.74% and 100%,45.16%,respectively.②Mean VI was 0.38 counts/cm~3 of malignant tumors and 0.18 counts/cm~3 of 31 benign tumors (P<0.05),The sensitivity and specificity in diagnosing malignant tumors of liver was 78.67% and 87.10%,respectively with VI>0.30 counts/cm~3.Conclusion The vascular pattern of 3D-CDE HI and VI>0.30 counts/cm~3 may be taken as parameters for the diagnosis of malignant liver tumor.
