| 目的 探讨经直肠超声造影增强模式在前列腺实性结节良恶性鉴别诊断中的应用价值。方法 分析经穿刺或手术病理证实的43例前列腺疾病患者共55个实性结节的经直肠超声造影(CETRUS)血流灌注特征,内容包括：增强时间、增强程度、消退时间、增强均匀度及增强后结节边界5个方面,比较良恶性结节在血流灌注特征上的差异。结果 55个实性结节病理证实33个恶性(恶性组)、22个良性(良性组)。恶性组与良性组比较,超声造影增强模式中快进、快出、不均匀增强、增强后结节的边界清晰4个观察指标差异有统计学意义(P<0.05)；恶性组与良性组在高增强造影表现上差异无统计学意义(P>0.05)。结论 CETRUS能够实时动态地观察前列腺结节的血流灌注情况,分析超声造影增强模式的特点,有助于提高超声对前列腺实性结节定性诊断的能力。 |

| Abstract: |
| Objective To investigate the application value of differentiating benign and malignant prostate solid nodules using contrast-enhanced trans-rectal ultrasonography by analyzing the enhancement modes. Methods The perfusion characteristics of contrast-enhanced trans-rectal ultrasonography (CETRUS) of total 55 solid nodules of 43 patients with prostate disease confirmed with puncturing or pathology, were analyzed from five aspects such as enhanced time, the degree of enhancement, regression time, enhanced homogeneity and the enhanced boundary, the differences of perfusion characteristics between benign and malignant nodules were compared relatively. Results With the pathological results as the gold standard, 55 prostate solid nodules were divided into malignant group including 33 nodules and benign group 22 nodules, there were statistical significances in benign and malignant nodules of rapid enhancement, rapid decrease, heterogeneous enhancement and well-defined boundary (P＜0.05); there was no significance in hyper-enhancement between the two group (P>0.05). Conclusion CETRUS can observe real-time dynamic perfusion of prostate nodules, analyzing the characteristics of enhancement patterns can help to improve the ability of ultrasonography in the diagnosis of prostate solid nodules. |
