ObjectiveTo investigate application value of parametric image processing in contrastenhanced ultrasound imaging in diagnosis of ovarian masses. MethodsFifty cases with ovarian masses underwent routine ultrasound and contrast-enhanced ultrasound imaging using a new dedicated parametric image processing software SonoLiver to analyze patterns of vascular formation and blood stream perfusion in the ovarian mass tissues on a digital video recorder in real time, compare their morphological characteristics of time-intensity curve (TIC) and dynamic vascular patterns (DVP) curve, and analyze quantitatively all indicators generated by SonoLiver.ResultsIn ultrasound imaging of the 50 cases, there were 24 cases (86％) displaying mainly blue lowly-enhanced imaging in those with benign masses and 15 cases (68％)displaying mainly red highly-enhanced imaging in those with malignant masses, with statistical significance (P ＜0. 01 ). There was significantly different characteristics of TIC and DVP between patients with benign and malignant masses. In 23 cases with benign masses, their DVP were significantly higher above the baseline than in those with malignant ones ( P = 0. 000), and in 15 cases with malignant lesions, their DVP were much shorter below the baseline than in those with benign ones, with statistical significance (P ＜0.05). The intensity of contrast medium, the time to reach its peak intensity and average transit time were all significantly higher in those with malignant masses than in those with benign ones (all P ＜ 0. 05 ). But, no statistical difference in the time of initial increasing between the two groups was found (P ＞ 0. 05). ConclusionsThere is significant difference in TIC and DVP of ultrasound imaging between benign and malignant masses, which if combined with contrast enhanced ultrasound parametric image processing can provide a more visualized quantitative information of benign and malignant ovarian masses with SonoLiver software.

Objective To evaluate the ability of contrast-enhanced ultrasonography (CEUS)in differentiate reactive lymph node,metastatic lymph node and lymphoma.Methods In a prospective study CEUS was performed in 129 patients with cervical lymph node enlargement.The entire process were recorded and preserved in DICOM format.The results were registered with Sonoliver.The receiver operating characteristic curve (ROC curve)analysis was performed to find the corresponding cutoff values. The selected node was removed surgically and submitted for histology.Results Of all the nodes,26 were reactive nodes,85 were metastases and 1 8 were lymphoma.Enhancement pattern was the most accurate way to characterize lymph nodes.The enhancement pattern of reactive lymph nodes was homogeneous and most of them were enhanced by lymphatic type while the metastatic lymph nodes were inhomogeneously enhanced or weakly enhanced by peripheral type.Lymph node lymphoma usually had no fixed enhancement pattern. Arrive time (AT),rise time (RT),time to peak (TTP),mean transit time (mTT),maximum intensity (IMAX),under the curve (AUC),rising slope(Kup),semi descending slope(Kdown)and perfusion index (PI)were significantly different in the three groups(P <0.05).RT,TTP and mTT of reactive lymph nodes were the shortest,which had significant difference compared with those of metastatic lymph nodes and lymphoma (P < 0.05 ).Kup,Kdown,IMAX%,AUC,PI in the reactive lymph nodes were significantly decreased compared with the metastatic group (P <0.05),but there was no significant difference compared with those in lymphoma (P >0.05 ).When TTP≥ 7.74 s,mTT≥26.54 s,metastatic lymph nodes were considered.When RT≥4.62 s,TTP ≥ 7.74 s,mTT ≥ 28.32 s,reactive lymph nodes were not considered. Conclusions Dynamic contrast-enhanced ultrasound image and enhancement pattern can distinguish neck lymph nodes while the optimal cut-off point time of the time-intensity curve parameters can further contribute to the identification of lymph nodes.
