- W2364754704 abstract "Objective To evaluate the diagnostic value of contrast-enhanced ultrasound(CEUS) in hepatic tumor and its clinical value in guiding radiofrequency ablation(RFA) in hepatic tumor. Methods Data of 56 patients with final diagnosis of hepatic tumor pathologically and having undergone RFA were analysed retrospectively. The positive diagnostic rates of contrast-enhanced computed tomography(CECT) and conventional ultrasound(two-dimensional ultrasound combined with Color Doppler flow imaging) were compared with those of CEUS. And the differences of the images of two-dimensional ultrasound and CEUS were analysed. The therapeutic effect of conventional ultrasound group(62 lesions) on the RFA treatment was also compared with that of CEUS group(50 lesions). Results In the 56 cases with 112 liver lesions(36 primary carcinomas and 76 metastasis), the positive diagnostic rates of CEUS, CECT and conventional ultrasound were 94.6%(106/112),96.4%(108/112) and 74.1%(83/112) respectively. There was no significant difference between CEUS and CECT examination(χ2=0.42,P0.05), but the difference between the conventional ultrasound group and the CEUS group was statistically significant)(χ2=17.9,P0.05). The rate of complete tumor ablation of RFA treatment by conventional ultrasound and CEUS were 69.4%(43/62) and 84%(42/50) respectively,but there was no significant difference between them(χ2=1.6,P0.05). Conclusion CEUS is really a practical and reliable diagnostic technique in making scheme before RFA treatment, guiding electrode position and evaluating the therapeutic efficacy after RFA treatment." @default.
