| 摘 要： | 目的:探讨3.0T MR动态增强扫描在鉴别乳腺导管原位癌和乳腺腺病中的价值。方法:研究纳入了经手术或穿刺活检证实的38例导管原位癌和40例乳腺腺病患者,对两组病变的MR多期动态增强表现进行回顾性对照分析,评价指标包括:强化形态、内部强化特点及时间-信号强度曲线,并对有统计学显著性差异的影像学征象的鉴别诊断价值进行分析。结果:导管样强化、节段样强化和肿块样强化多见于导管原位癌(P=0.04,0.04,0.02)。区域性强化和弥漫性强化多见于乳腺腺病(P=0.03,0.02)。点簇样强化及边缘强化多见于导管原位癌(P=0.02,0.03)。不均匀性强化多见于乳腺腺病(P=0.04)。速升缓降型曲线和速升平台型曲线多见于导管原位癌(P=0.03,0.02),持续缓升型和缓升平台型多见于腺病(P=0.03,0.04)。病变强化形态的鉴别诊断价值要高于内部强化特点和时间-信号强度曲线,其敏感度、特异度及准确度分别为69.2%、71.2%和70.4%。结论:3.0T MR动态增强扫描有助于鉴别导管原位癌和乳腺腺病,病变强化形态的鉴别诊断价值要高于内部强化特点和时间-信号强度曲线。
