Abstract:
Objective To explore the application value of dynamic vascular patterns(DVP) curve and parameter figure in the focal liver lesions by contrast-enhanced ultrasound(CEUS).Methods 83 cases of focal liver lesions diagnosed by pathologically or clinically that had undergone CEUS were analyzed by SonoLiver software.Then DVP parametric images were constructed and the time-intensity curve (TIC) parameters were calculated by TIC and DVP curve.Results Rise time(RT),time to peak(TTP),maximum intensity(IMAX),mean transit (mTT),slope of rise,and the absolute value for slope of half down between malignant and benign lesions groups indicated statistically significant difference (P ＜0.05).94.9％ of type Ⅰ was malignant lesions and 100％ Ⅳ type was benign lesions.The four types of DVP curve(Ⅰ,Ⅱ,Ⅲ,Ⅳ)in malignant and benign lesions were 72.5％,13.7％,13.7％,0 and 6.2％,43.8％,31.2％,18.8％,respectively.The proportion and characteristic of DVP parametric images and DVP curves in malignant and benign lesions groups were consistent.Conclusions DVP curve and parametric images of CEUS can demonstrate the difference of flow perfusion static between lesions area and surrounding liver parenchyma dynamically and directly.These are new qualitative indexes of the differential diagnosis in focal liver lesions.
