摘　　要：目的:探讨胎盘植入侵犯宫颈的MRI表现。方法:回顾性分析9例经病理证实的胎盘植入侵犯宫颈患者(宫颈侵犯组)的MRI表现,与9例无侵犯宫颈证据的胎盘植入患者(对照组)进行比较分析。结果:宫颈侵犯组和对照组各有8例和3例表现为宫颈缩短,各有6例和1例表现为宫颈内口扩张;各有5例和0例表现为胎盘突入到宫颈管内口,各有4例和0例表现为有胎盘组织突入宫颈壁内;以上征象在两组间的发生率差异均有统计学意义(P<0.05)。结论:胎盘植入侵犯宫颈的MRI征象可能为宫颈缩短、宫颈管内口扩张、胎盘突入到宫颈管内口、胎盘组织突入宫颈壁内等。Objective： To study the MRI features of placenta accreta with cervical invasion. Methods：MRI findings of 9 patients with pathology proven placenta accreta in combination with cervical invasion （study group） were retrospectively analyzed. The MRI features were compared with other 9 cases of placenta accreta without cervical invasion （control group）. Results：There were 8 patients of study group and 3 patients of control group showing shortened cervix,internal os dilation could be revealed in 6 patients of study group and 1 patient of control group;5 patients with placental protrusion into internal os and 4 patients with placental invasion of cervical wall could be assessed in the study group, yet no such feature was seen in the control group. The above mentioned findings showed statistic difference between these two groups （P〈0.05）. Conclusion：The MRI features of placenta accreta with cervical invasion might include shortened cervix,internal os dilation, placenta protrusion into internal os and placenta invasion of cervical wall.
