【摘要】：目的:聲觸診組織定量技術(shù)(VTTQ)是一種檢測組織硬度的新技術(shù)。本研究的目的是比較VTTQ和直腸指診(DRE)之間對于前列腺癌(PCa)和良性前列腺增生(BPH)的效能。方法:VTTQ用于檢測60例BPH和疑似PCa患者,每一個(gè)病灶通過聲輻射脈沖(ARFI)激發(fā)并測量相應(yīng)病變的剪切波速(SWV)值。測值與病理結(jié)果對照,對VTTQ和DRE鑒別PCa和BPH之間的診斷效能進(jìn)行比較。結(jié)果:PCa和BPH組織的SWV值(m蛐s)明顯大于正常前列腺組織(2.97±0.42,2.61±0.47,2.46±0.52),差異有顯著性。在ROC曲線中,以SWV2.87 m蛐s為診斷標(biāo)準(zhǔn),VTTQ診斷前列腺良惡性病變的曲線下面積(AUC)為0.78,而DRE是0.67。VTTQ診斷PCa的敏感性、特異性、陽性預(yù)測值、陰性預(yù)測值和準(zhǔn)確性分別為80.0%,66.7%,74.3%,72.0%,79.2%,而DRE分別為57.5%,52.3%,62.5%,57.0%,62.1%。結(jié)論:VTTQ可以有效地檢測前列腺結(jié)節(jié)病變的硬度,在鑒別PCa和BPH方面比DRE具有更高的診斷效能。
[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 鹵0.42n 2.61 鹵0.47U 2.46 鹵0.52), and the difference was significant.鍦≧OC鏇茬嚎涓，
