Conclusion: After the administration of hCG there was a visible increase in perifollicular capillary network volume, relative volume of blood, and balancing of blood inflow of each feeding vessel of the perifollicular circulation.

The paper describes a prototype of automated quantitative assessment of perifollicular vascularisation. The proposed algorithm works with 3D power Doppler ultrasound images and consists of (a) searching the position and shape of the dominant follicle by utilising the continuous wavelet transform; (b) categorizes the vessels contained in 5 mm thick layer around the follicle by defining larges possible spheres within the vessels. The results are statistically evaluated. To visually improve the vessel reconstruction, minimal spanning trees are deployed at the end.

The influence of noise on rigid registration of ultrasound volumes is studied in this paper. Binary volumes result from a segmentation of ovarian ultrasound volumes. Rigid registration is preformed in frequency domain. The calculation of rotation is done using the amplitude spectrum and sphere correlation. The method’s performance was systematically assessed by changing the number of follicles, their position, orientation and size. Hundred volume pairs were involved in each experiment. The method proved sensitive to changes of follicle size but resistive to other kinds of destruction.

This study represents the most comprehensive audit of individualized ART in clinical practice in Central and Eastern Europe. Overall, clinical pregnancy was achieved by 39.5% of patients after stimulation with follitropin alfa. The use of follitropin alfa FbM resulted in a higher cumulative pregnancy rate than did the FbIU formulation. Limitations of the study include the observational and non-comparative study design, and descriptive nature of statistical analyses.

Conclusions: In this study we have shown that in normal intrauterine pregnancy after IVF/ET, prominent endometrial volume growth can be detected by a three-dimensional ultrasound over the course of several days. Moreover, in patients who did not conceive in a particular cycle, a decrease in endometrial volume can be seen.
