OP18.10: Automated three‐dimensional follicular measurements increase the clinical work flow in an IVF programme

Abstract

(endometrial irrigation day) and 12th days after first menstrual day. The 2D power Doppler mid-sagittal uterine images (at peak systolic and end-diastolic vascular filling) were obtained under standard sonographic preset. The endometrial region of interest (ROI) was defined in the images. Mean endometrial color intensity (CI) and endometrial vascular ratio (VR) (color/total pixels in the ROI) were calculated by a special computer program for the systolic and diastolic images. CI and VR systolic-to-diastolic ratios were further calculated (S/D-CI and S/D-VR). Results: S/D-VR decreased significantly from the 5th to the 12th day NSI cycles (1.87 ± 0.54 to 0.69 ± 0.27, correspondingly), p-value < 0.05. Post-irrigation results of S/D-VR were significantly higher in OSI compared to NSI (1.59 ± 0.47 and 0.69 ± 0.27), p-value < 0.05. S/D-CI did not change significantly along the studied days and were similar in NSI and OSI cycles. Conclusions: S/D-VR decreases along the follicular phase in NSI cycles in contrast to the post-irrigation increase in S/D-VR in OSI cycles. Several speculative explanations may be suggested for such endometrial vascular response.
