Abstract:
Objective To assess the diagnostic performance of real-time contrast-enhanced ultra-sound Sonovuein diagnosing minute rabbit liver VX 2 tumors with diameter ≤10.0 mm.Methods Thir-ty New Zealand white rabbits inoculated with VX 2 tumor ( left, right lobe of each ) were examined by two-di-mensional ultrasound and CEUS .The contrast enhanced mode of small rabbit liver VX 2 tumors in different phase was observed and tumor in the rabbit's liver was pathologically verified .The diagnostic performances of two-dimensional US and CEUS in detecting the rabbit VX 2 tumors were analyzed and compared .Results Thirty-nine tumors were pathologically verified .The detection rates of small tumors by CEUS and two-di-mensional US were 12.8% and 79.5%, respectively , yielded significantly higher than that of 2-D US. Conclusion Real-time CEUS significantly improves the detection rates of small rabbit VX 2 liver tumors less than 10.0 mm in diameter .
