Abstract:
Objective To assess the ability of three-dimensional contrast-enhanced ultrasonography (3D-CEUS) and quantitative analysis in differential diagnosis of focal liver lesions ( FLL) . Methods The quantitative analysis technique was used to deal with the dynamic 3D-CEUS raw data of FLL ,which were confirmed by clinical or pathological diagnosis . The corresponding time-intensity curve and parameters were obtained . The parameters were compared to confirm whether there existed any difference in the parameters between benign and malignant FLL . Results Seventy-three FLL were enrolled including 59 malignant and 14 benign lesions . The differences of the parameters between benign and malignant groups were statistically significant ,including area under the curve ( A) ( 169 .58 ± 95 .46 vs 71 .26 ± 64 .13) ,area under the curve of wash-in(AWI)(22.84±18.37vs9.96±10.01) ,andareaunderthecurveofwash-out(AWO)(146.73± 82 .03 vs 61 .29 ± 55 .06) (all P <0 .05) . The other quantitative parameters showed no significant difference (all P > 0 .05) .Conclusions The quantitative analysis can be used to identify benign and malignant FLLs on 3D-CEUS .
