目的：探讨腹部加压法对于提高经直肠前列腺结节超声弹性成像稳定性的临床应用价值。方法分别在常规和腹部加压两种情况下，用超声弹性成像技术对77个前列腺结节进行评分，得出弹性变化率比值SR和SR1，结合病理结果，计算两种情况下的敏感度、特异度、准确度、阳性预测值和阴性预测值。结果腹部加压情况下所得特异度（92.4%）、准确度（87.4%）高于常规方法（88.5%、84.4%）。结论腹部加压方式时经直肠前列腺超声弹性成像技术所得参数结果更为稳定客观。“,”Objective To assess the clinical application value of abdominal pressure method on transrectal ultrasound elastog-raphy examination of prostate nodule. Methods SR and SR1 were produced after examined prostate nodules using transrectal ul-trasound elastography technique with conventional method and abdominal pressure method,and the sensitivity,specificity,accu-racy,positive predictive value and negative predictive value were calculated according to the examination results. Results The specificity and accuracy with abdominal pressure method were 92. 4% and 87. 4%,which were significantly higher than 88. 5%and 84. 4% of the conventional groups( P 0. 05). Conclusion Abdominal pressure method have high stability and reliability when conducting transrectal ultrasound elastography examination of prostate nodules.
