| 目的 探讨经直肠超声三维显像(3D-TRUS)在前列腺良、恶性结节诊断中的价值。方法 对72例前列腺结节患者行CDFI及3D-TRUS检查,对声像图表现行血管半定量分型和血管指数(VI)定量分析。结果 ①恶性结节在部位、边界、回声类型以及对包膜和前列腺对称性的影响等方面,与良性结节差异显著(P＜0.01);②经直肠三维彩色血管能量成像(TR3D-CPA)显示前列腺癌(PCa)较良性病变血管丰富、增粗、走行纡曲、紊乱。以TR3D-CPA Ⅳ级诊断PCa,敏感性为78.38%,特异性为81.03%;PCa的VI值明显高于良性病变(P＜0.001)。结论 3D-TRUS可为鉴别诊断前列腺良、恶性结节提供丰富的诊断信息。 |

| Objective To assess the value of three-dimensional transrectal ultrasonography (3D-TRUS) in diagnosing benign and malignant prostate nodules. Methods A total of 72 patients with prostate nodules underwent CDFI and 3D-TRUS. Ultrasonographic images were analyzed half-quantitatively, and quantitative analysis of vascularity pattern and vascularity index (VI) was performed. Results ①There were obvious differences between benign and malignant nodules in the position, border, echo and effects on the envelope and symmetry of prostate (P<0.01); ②Transrectal three-dimensional color power angiography (TR3D-CPA) displayed richer, more tortuous and disordered vascularity in prostate cancer (PCa) than in benign lesions. In diagnosis of PCa, the sensitivity and specificity of TR3D-CPA Ⅳ was 78.38% and 81.03%, respectively. VI of PCa was significantly higher than that of benign lesions (P<0.001). Conclusion 3D-TRUS can provide abundant information for the differential diagnosis of benign and malignant prostate nodules. |
