According to earlier studies, radiographic evidence of polypoid filling defects in the uterine cavity has a physiological background if hysterography is carried out during the secretory phase of the menstrual cycle, but if performed during the proliferative phase, the defects indicate endometrial hyperplasia. This view was not confirmed in the present investigation. Of 8,000 hysterograms reviewed, 200 (2.5%) showed filling defects. Of these, 162 hysterograms were from cases in which the coexisting histological appearance of the endometrium was available; 78% of the histological examinations showed no abnormalities. There was no difference between the secretory and proliferative phases in this respect, and no correlation between radiographic evidence of polypoid filling defects and abnormal uterine bleeding.
根据早期研究，如果在月经周期的分泌期进行子宫输卵管造影，宫腔内息肉样充盈缺损的影像学证据具有生理背景，但如果在增殖期进行，则这些缺损提示子宫内膜增生。本研究未证实这一观点。在回顾的8000份子宫输卵管造影图中，200份（2.5%）显示有充盈缺损。其中，162份子宫输卵管造影图来自有子宫内膜并存组织学表现的病例；78%的组织学检查未显示异常。在这方面，分泌期和增殖期之间没有差异，息肉样充盈缺损的影像学证据与异常子宫出血之间也没有相关性。
