Re: follicle and oocyte ultrasound studyFrom: DuBose, Terry (DuboseTerryJ@uams.edu)Mon Jul 30 15:38:06 2001
Dear P.Pellizzari. I have two suggestions... first go to OBGYN.net (http://www.obgyn.net/medline.asp) and register there, and do a search. I used "studies concerning the follicle and the oocytes using both pulsed and color Doppler and 3d ultrasound" and got RESULT SET: 200 documents displayed out of 1266027 documents found. The following two references were at the top of the list, using "Relevency". Now specifically, who is doing research in the subject of Doppler of the ovaries?... I am sure there are many. But I would first start with Professor Stuart Campbell's group in the UK (see abstracts below). Others work to look for are Asim Kurjak (Zagreb, Croatia), Art Fleischer (Vanderbilt Univ. Nashville Tennessee, USA), and Kenneth Taylor (Yale Univ, USA). Hope this helps. The following sentence from Professor Campbell's 2nd abstract below is very interesting. "There is growing evidence that studies of peri-follicular vascularity will predict the development of a healthy oocyte and subsequently an embryo." If anyone knows more about this research, please tell us about it. I do not have access to the British Medical Bulletin. Thanks. Peace, Terry J.

AB - The US diagnostic criteria of the PCO have been refined with each successive advance in US technology. Diagnostic accuracy has evolved from a mere appreciation of overall ovarian size to the recognition of characteristic follicular patterns of distribution and subtle textural changes in the ovarian stroma. The most consistent features are the presence of multiple small follicles arranged around, or scattered through, a dense echogenic ovarian stroma, although recognition of the latter is highly subjective. Sophisticated innovations such as 3D US, together with colour and pulsed Doppler US, should improve the objectivity of observations and allow quantitative analysis of the ovarian stroma, which is known to be the source of the characteristic hyperandrogenaemia in PCOS. Valid comparative studies of women with normal and polycystic ovaries should now be feasible and will hopefully bring us closer to understanding the pathogenesis of this fascinating condition.

AB - Current data demonstrate that angiogenesis in the ovaries and uterus is an essential component of both follicular and luteal phases of menstrual cycle, tightly correlating with the levels of bioactive substances such as hormones, growth factors and interleukins. Ultrasound is used principally to demonstrate follicular growth, a receptive triple layer endometrium and to exclude pathologies such as fibroids and ovarian tumours. However, the development of new technologies such as CDI, CPA, 3D-US, 3D-CPA is now set to expand the role of ultrasound in the assessment of the processes in the ovaries, uterus and early pregnancy. There is growing evidence that studies of peri-follicular vascularity will predict the development of a healthy oocyte and subsequently an embryo. Endometrial blood flow studies with conventional CDI and the newer techniques of CPA and 3D-CPA will be important in predicting endometrial receptivity. Ovarian stromal vascularity appears to correlate with vascular endothelial growth factor (VEGF) levels and high vascularity is associated with PCO and a risk of ovarian hyperstimulation syndrome. 3D-CPA may improve our ability to assess ovarian and endometrial vascularization and blood circulation, to diagnose tubal patency. Increasingly, 3D ultrasound is being applied to diagnose the pathology of early singleton and multiple pregnancies.

Do you know if there is a University department of obstetrics and gynaecology which is making this kind of research ? I would be very grateful if I could contact them Thank you P.Pellizzari

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
