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 mm 2/s;基质平均ADC值为(1.50±0.43)×10-3 mm 2/s,与对照组[(1.37±0.06)×10-3 mm 2/s及(1.27±0.08)×10-3 mm 2/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。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 mm 2/s and the mean ADC value of cervical stromal layer was(1.50±0.43)×10-3 mm 2/s in observation group,while in control group was(1.37±0.06)×10-3 mm 2/s and(1.27±0.08)×10-3 mm 2/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.
