【摘要】：目的:声触诊组织定量技术(VTTQ)是一种检测组织硬度的新技术。本研究的目的是比较VTTQ和直肠指诊(DRE)之间对于前列腺癌(PCa)和良性前列腺增生(BPH)的效能。方法:VTTQ用于检测60例BPH和疑似PCa患者,每一个病灶通过声辐射脉冲(ARFI)激发并测量相应病变的剪切波速(SWV)值。测值与病理结果对照,对VTTQ和DRE鉴别PCa和BPH之间的诊断效能进行比较。结果:PCa和BPH组织的SWV值(m蛐s)明显大于正常前列腺组织(2.97±0.42,2.61±0.47,2.46±0.52),差异有显著性。在ROC曲线中,以SWV2.87 m蛐s为诊断标准,VTTQ诊断前列腺良恶性病变的曲线下面积(AUC)为0.78,而DRE是0.67。VTTQ诊断PCa的敏感性、特异性、阳性预测值、阴性预测值和准确性分别为80.0%,66.7%,74.3%,72.0%,79.2%,而DRE分别为57.5%,52.3%,62.5%,57.0%,62.1%。结论:VTTQ可以有效地检测前列腺结节病变的硬度,在鉴别PCa和BPH方面比DRE具有更高的诊断效能。
[Abstract]:Objective: acoustic palpation tissue quantitative technique (VTTQ) is a new technique for detecting tissue hardness.The aim of this study was to compare the efficacy between VTTQ and digital rectal examination for prostate cancer (PCA) and benign prostatic hyperplasia (BPH).Methods VTTQ was used to detect 60 patients with BPH and suspected PCa. Each lesion was stimulated by acoustic pulse ARFI and the shear wave velocities were measured.The diagnostic efficacy of VTTQ and DRE in differentiating PCa from BPH was compared with pathological results.Results the SWV value of BPH and PCA was significantly higher than that of normal prostate tissue (2.97 卤0.42n 2.61 卤0.47U 2.46 卤0.52), and the difference was significant.鍦≧OC鏇茬嚎涓，
