【摘要】：目的探讨声脉冲辐射力弹性成像(ARFI)声触诊组织定性成像(VTI)在肝癌射频消融(RFA)疗效评价中的临床价值。方法收集行RFA的73例肝癌患者共82个病灶作为研究对象。RFA后采用常规超声、VTI、超声造影(CEUS)和增强CT(CECT),测量消融灶最大长径及其垂直径,并对4种检查方法的结果进行比较。结果常规超声、VTI、CEUS和CECT测得消融灶面积分别为(5.4±3.26)、(14.21±7.35)、(14.31±7.04)和(13.18±7.24)cm2。VTI测值与常规超声比较,差异有统计学意义(P0.05);VTI与CEUS、CECT比较,差异无统计学意义(P0.05);对VTI获取的消融灶面积与CEUS、CECT测量结果进行相关分析,具有较高的相关性(r=0.987,r=0.959,P0.05)。结论 VTI能清晰显示消融灶的边界,较准确地判断肝消融灶的大小,对评价肝癌RFA疗效具有重要应用价值。
[Abstract]:Objective to evaluate the clinical value of acoustic pulse radiation-force elastic imaging (ARFI) in evaluating the effect of radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC). Methods Eighty-two lesions were collected from 73 patients with hepatocellular carcinoma treated with RFA. The results were compared with the results of the four methods. The maximum length and vertical diameter of the ablation focus were measured by conventional ultrasound VTI (contrast-enhanced CECT) and enhanced CTE CT. Results the ablation area measured by VTICEUS and CECT were 14.21 卤7.35 and 14.31 卤7.04, respectively, and 13.18 卤7.24)cm2.VTI were significantly different from those of conventional ultrasound. There was no significant difference (P 0.05), and there was a high correlation between the area of ablation area obtained by VTI and the results of CECT measurement of CECT. There was a high correlation between the area of ablation and the results of CECT obtained by VTI, and there was a high correlation between the area of ablation and the measurement of CECT by CECT. Conclusion VTI can clearly show the boundary of ablation focus and accurately judge the size of hepatic ablation focus. It has important application value in evaluating the curative effect of liver cancer RFA.
