联合经直肠实时超声弹性成像与超声造影在前列腺癌诊断中的应用价值

Value of transrectal real-time elastography and contrastenhanced ultrasound in imaging of prostate cancer

目的探讨经直肠实时超声弹性成像(TRTE)、超声造影(CEUS)单一及联合应用对前列腺癌的诊断价值。方法回顾性分析疑似前列腺癌患者34例,行TRTE和CEUS检查,并以前列腺穿刺活检或术后病理结果为金标准,比较二者单一及联合应用对前列腺癌的诊断价值。结果TRTE诊断前列腺癌准确率64.7%(22/34),敏感度78.6%(22/28),特异度50%(3/6);CEUS诊断前列腺癌准确率55.9%(19/34),敏感度67.9(19/28),特异度33.3(2/6);TRET+CEUS诊断前列腺癌准确率73.5%(25/34),敏感度89.3%(25/28),特异度66.7%(4/6)。TRTE、CEUS、二者联合应用准确率、敏感度及特异度比较差异无统计学意义。结论 TRTE和CEUS诊断前列腺癌各具优势,二者联合应用可提高前列腺癌诊断的准确率、敏感度及特异度。

Objective To evaluate the value of transrectal real-time elastography and contrast-enhanced ultrasound in imaging of prostate cancer.Methods Retrospective analysis about34patients with suspected prostate cancer,underwent TRTR and CEUS,compared with postoperative pathology,evaluate the value of each method.Results The accuracy,sensitivity and specificity of TRTE in prostate cancer were64.7%(22/34),78.6%(22/28),50%(3/6),respectively.The accuracy,sensitivity and specificity of CEUS in prostate cancer were55.9%(19/34),67.9%(19/28),33.3%(2/6),respectively.The accuracy,sensitivity and specificity of TRTE+CEUS in prostate cancer were73.5%(25/34),89.3%(25/28),66.7%(4/6),respectively.There was no significant difference in accuracy and sensitivity.Conclusion TRTE and CEUS diagnosis of prostate cancer have their own advantages,the two combined application can improve the accuracy,sensitivity and specificity of prostate cancer.
