本研究探讨回波去相关成像，热消融监测的超声方法。在离体牛肝组织上进行的射频消融实验中，评估了组织温度对标测回波去相关参数的影响。回波去相关图与相应的组织温度模拟使用有限元方法进行了比较。对于回波去相关成像和背向散射积分成像，映射的组织参数与局部组织温度显著但弱相关。使用受试者工作特征（ROC）曲线评估回波去相关和背向散射积分预测组织温度高于40、60和80°C的能力。与背向散射积分成像（AUROC = 0.865、0.877和0.832）相比，使用回波去相关成像（AUROC = 0.871、0.948和0.966）预测组织温度大于40、60和80°C时，获得了显著更高的ROC曲线下面积（AUROC）值。
This study investigates echo decorrelation imaging, an ultrasound method for thermal ablation monitoring. The effect of tissue temperature on the mapped echo decorrelation parameter was assessed in radiofrequency ablation experiments performed on ex vivo bovine liver tissue. Echo decorrelation maps were compared with corresponding tissue temperatures simulated using the finite element method. For both echo decorrelation imaging and integrated backscatter imaging, the mapped tissue parameters correlated significantly but weakly with local tissue temperature. Receiver operating characteristic (ROC) curves were used to assess the ability of echo decorrelation and integrated backscatter to predict tissue temperature greater than 40, 60, and 80°C. Significantly higher area under the ROC curve (AUROC) values were obtained for prediction of tissue temperatures greater than 40, 60, and 80°C using echo decorrelation imaging (AUROC = 0.871, 0.948 and 0.966) compared to integrated backscatter imaging (AUROC = 0.865, 0.877 and 0.832).
