摘　　要：目的探讨经直肠实时超声弹性成像(TRTE)技术在前列腺良恶性病变鉴别诊断中的价值。方法对52例疑诊为前列腺癌的患者行经直肠超声检查(TRUS)及TRTE检查,分别将TRUS及TRTE检查结果与病理检查结果进行比较,评价两种检查方法的一致性。结果 TRUS检查与病理检查结果进行Kappa检验,K=0.741,诊断符合率84.1%;TRTE检查与病理检查结果进行Kappa检验,K=0.894,诊断符合率93.6%。两种方法检查结果诊断符合率比较差异有统计学意义(P<0.05)。结论 TRTE技术可以检测出更多的肿瘤病灶和Gleason分级较高的恶性病灶,对鉴别诊断前列腺良恶性病变具有重要的价值。Objective To assess the value of transrectal real-time tissue elastography（TRTE）in the diagnosis of benign and malignant prostatic diseases. Methods Fifty-two patients were suspected with prostatic cancer found in laboratory or clinical examinations underwent prostatic biopsies. All subjects underwent transrectal ultrasonography（TRUS）and TRTE before biopsies.Kappa test was made to check the consistency of TRTE,TRUS and pathologic methods. Results The Kappa value was 0.741 between pathologic diagnosis and TRUS,and the consistency with pathology was 84.1%. The Kappa value was 0.894 between pathologic and TRTE,and the consistency was 93.6%. Conclusion More tumor lesions and higher Gleason grading malignant lesions are detected by TRTE,this technique is helpful in the differential diagnosis of prostatic diseases with a broad application prospect.
