      超声剪切波弹性成像引导前列腺穿刺的应用

      Application of shear wave elastography in guiding prostate puncture

      摘要:
      目的:探讨剪切波弹性成像技术(SWE)在提高前列腺癌检出率中的作用及意义.方法:对76例临床可疑前列腺癌患者行常规10针穿刺的基础上加穿SWE异常区,通过对比穿刺结果,探讨SWE在提高前列腺癌检出率中的作用.结果:76例患者全部完成穿刺,病理诊断前列腺癌32例,良性病变44例.系统穿刺法阳性例数为25,检出率32.89%;SWE异常处穿刺阳性例数为28例,检出率36.84%.10点系统穿刺针数为760针,阳性针数为84针,单针检出率11.05%;SWE异常处穿刺针数为112针,阳性针数为76针,单针检出率67.86%,明显高于10点系统穿刺法(P<0.05).SWE对76例疑似前列腺癌患者检测的敏感度为87.50%,特异度为86.36%,准确性为86.84%,阳性预测值为82.35%,阴性预测值为90.48%.结论:SWE有助于确定活检靶目标,有效提高前列腺癌检出率.
      Abstract:
      Objective:To evaluate the effect and significance of shear wave elastography (SWE) in improving the detection rate of prostate cancer.Methods:Seventy-six cases of clinically suspected prostate cancer patients included.System 10-point puncture plus SWE exception handling puncture were used,discuss the role of SWE in improving the detection rate of prostate cancer by comparing the results of puncture.Results:Seventy-six cases of suspected prostate cancer patients were successfully punctured.The pathologically confirmed prostate cancer in 32 cases,benign lesions in 44 cases.10-point system was positive in 25 cases,about 32.89% and SWE puncture positive anomaly at 28 cases,about 36.84%.The number of 10-point system were 760 and the number of positive were 84,the single needle positive rate was 11.05%.The number of SWE were 112 and the number of positive were 76,the single needle positive rate was 67.86%,significantly higher than 10-point system (P<0.05).The sensitivity of SWE for detection of 76 patients with suspected prostate cancer was 87.50%,specificity 86.36%,accuracy 86.84%,the positive predictive value 82.35%,the negative predictive value 90.48%.Conclusions:SWE can help identify targets for biopsies and improve the detection rate of prostate cancer.
