摘要 目的 探讨动态增强磁共振(DCE-MRI)在前列腺良恶性肿瘤鉴别诊断中的应用价值.方法 对2017年6月~2019年3月保定市第一中心医院分别行常规MRI、DCE-MRI和病理检查的70例前列腺疾病男性患者的临床资料进行回顾性分析.以病理穿刺活检结果为金标准评估常规MRI和DCE-MRI对诊断前列腺良恶性肿瘤的敏感性、特异性及准确性.根据DCE-MRI图像特点,比较定量参数转运常数(Ktrans)、速率常数(Kep)、细胞外间隙体积分数(Ve)间的差异.结果 DCE-MRI对诊断前列腺良恶性肿瘤的敏感性、特异性及准确性分别为90.48%、79.59%和82.86%均高于常规MRI检查;经DCE-MRI诊 断为PCa的患者,其Ktrans、Kep和Ve参数值均高于诊断为BPH的患者(P<0.05).结论 DCE-MRI对诊断前列腺良恶性肿瘤的敏感性、特异性及准确性较高,建议作为PCa病理检查和常规MRI检查的补充手段应用于临床.
