中文摘要:
      目的 观察MRI检测早产高危孕妇宫颈变化的可行性。方法 收集20例早产高危孕妇(观察组)和20例非早产孕妇(对照组)。对比分析2组宫颈基质及腺下区T2WI及DWI信号、宫颈长度、内口宽度及ADC值。结果 观察组宫颈长度明显缩短,平均(25.16±15.68)mm;宫颈内口宽度扩大呈喇叭口状,平均(20.46±1.82)mm;宫颈腺下区矢状位T2WI及DWI信号增高,宫颈腺下区平均ADC值为(1.87±0.52)×10-3 mm2/s;基质平均ADC值为(1.50±0.43)×10-3 mm2/s,与对照组[(1.37±0.06)×10-3 mm2/s及(1.27±0.08)×10-3 mm2/s]比较差异有统计学意义(P均<0.05)。结论 MRI可显示早产高危孕妇宫颈变化,对早期预测和临床干预早产具有重要价值。
英文摘要:
      Objective To observe cervical changes in pregnant women at high risk of preterm delivery with MRI. Methods Twenty high-risk preterm women (observation group) and 20 non-preterm women (control group) were collected. T2WI and DWI signals, cervical length, the width of inner cervix and ADC values were measured and compared between 2 groups. Results In observation group, the length of cervix was significantly shorten, with an average (25.16±15.68)mm, while the width of inner cervix was widen like bell-mouthed, with an average (20.46±1.82)mm. On sagittal T2WI and DWI, signal of in subglandular region increased in observation group. The mean ADC value of cervical subglandular region was (1.87±0.52)×10-3 mm2/s and the mean ADC value of cervical stromal layer was (1.50±0.43)×10-3 mm2/s in observation group, while in control group was(1.37±0.06)×10-3 mm2/s and(1.27±0.08)×10-3 mm2/s, respectively (both P<0.05). Conclusion MRI can display cervical changes of pregnant women at high risk of preterm delivery, having great value for early prediction and clinical intervention of premature delivery.
