Changes in perifollicular vascularity after administration of human chorionic gonadotropin measured by quantitative 3-D power Doppler ultrasound.

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.

Samodejna kvantitativna ocena perifolikularne vaskularizacije z uporabo ultrazvočnih slik močnostnega dopplerja

V prispevku opisujemo prototip avtomatiziranega ocenjevanja perifolikularnega ožilja. Predlagani postopek uporablja 3D dopplerjeve ultrazvočne slike in sestoji iz dveh korakov: išče položaj in obliko dominantnih jajčnih mešičkov, pri čeme uporablja zvezno valčno transformacijo, in kategorizira žile, oddaljene do 5 mm od mešička, z maksimalnimi možnimi sferami v njih. Statistični rezultati so predstavljeni v obliki histogramov za žilne premere. Za občutno izboljšan prikaz 3D rekonstrukcije so bila uporabljena minimalna vpeta drevesa.

Vpliv šuma na rezultate pri poravnavanju segmentiranih jajčnih volumnov s sferično korelacijo v frekvenčnem prostoru

Prispevek obravnava vpliv šuma na poravnavanje ultrazvočnih volumnov. Binarni volumni izhajajo iz segmentacije ultazvočnih posnetkov jajčnikov. Toga poravnava je bila izvedena v frekvenčnem prostoru. Rotacijo smo izračunavali s pomočjo amplitudnega spektra in sferične korelacije. Uspešnost metode smo ocenili s sistematičnim preverjanjem, tako da smo spreminjali število mešičkov ter njihove položaj, usmeritev in velikost. V poskus je bilo vključenih sto parov volumnov. Potrdili smo občutljivost metode na velikost mešičkov in njeno neodvisnost od ostalih popačitev.

An observational study of assisted reproductive technology outcomes in new EU member states: an overview of protocols used for ovarian stimulation.

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.

Endometrial growth in early pregnancy after IVF/ET.

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.
