To determine what, if any, changes occur in the appearance of the uterus on magnetic resonance (MR) images after dilation and curettage (D&C), nine women without endometrial abnormality underwent imaging before D&C and on day 2 and day 7 after D&C. On day 2, markedly hypointense curvilinear areas in the endometrial canal were noted on MR images in all patients (P = .0002). By day 7, these areas decreased in size in five (62%) and completely resolved in the rest (P = .022). There was no significant change in the width of the endometrial stripe or in the width or signal intensity of the junctional zone or myometrium after D&C. The junctional zone was focally disrupted in one patient who underwent D&C that was complicated by a uterine perforation. Therefore, curvilinear areas of low signal intensity (most likely representing clot) in the endometrial canal were visualized on MR images within 2 days of uncomplicated D&C and decreased in size or resolved over time. Significant widening of the endometrial stripe or disruption of the junctional zone was not observed after uncomplicated D&C.
为了确定刮宫术（D&C）后子宫在磁共振（MR）图像上是否出现任何变化，九名无子宫内膜异常的女性在刮宫术前以及刮宫术后第2天和第7天接受了成像检查。在第2天，所有患者的MR图像上均在子宫内膜管内发现明显的低信号曲线区域（P = .0002）。到第7天，其中五个（62%）的这些区域尺寸减小，其余区域完全消失（P = .022）。刮宫术后子宫内膜条带的宽度、结合带或肌层的宽度或信号强度均无显著变化。一名接受刮宫术并发子宫穿孔的患者的结合带出现局灶性中断。因此，在未并发的刮宫术后2天内，MR图像上可显示子宫内膜管内低信号强度的曲线区域（最可能代表血凝块），且这些区域会随着时间推移尺寸减小或消失。未并发的刮宫术后未观察到子宫内膜条带显著增宽或结合带中断。
