A study that took six years in the making shows a 10% improvement in in-vetro fertilization, which is very good news for makers of 4D ultrasound. Largely used in research and "entertainment" purposes, the OB/GYN market has been looking for more applicable uses for 4D ultrasound. While very helpful in many studies, its not-so-real-time "real time 4D" has proved to be challenging in its cost-effectiveness as a diagnostic tool. This is the likely the first in many justifications for 4D ultrasound imaging in the OB/GYN market. The full article is found here.

3D/4D ultrasound improves IVF
The pregnancy rate for patients undergoing in-vitro fertilization (IVF) is improved when doctors use advanced 3D/4D imaging to guide the placement of embryos to the point where the endometrium is most receptive to implantation, according to a study presented today at the 63rd annual meeting of the American Society for Reproductive Medicine.
The study, “Maximal Implantation Potential (MIP) Point -- Suggested Target for Optimal Embryo Placement Within the Uterine Cavity During Embryo Transfer,” was led by Robert Gergely, MD.
Gergely has identified a new embryo placement target as the point where the fallopian tubes would intersect if they were extended beyond their natural length. The new target, or MIP point, is where embryos typically implant and develop in natural pregnancies.
The six-year retrospective, observational study, conducted at the 3D Sonography Center of Beverly Hills, evaluated 5,073 patients with a mean age of 38.3 years who received IVF using 3D/4D-guided embryo transfer. In each case, embryo placement was targeted at the MIP point.
The patients participating in the study achieved an overall pregnancy rate of 40.34 percent, which is 10.04 percent higher than the rate achieved prior to the introduction of the 3D/4D-guided MIP point technique in 2001. Earlier study results based on 1,222 patients were published in the August 2005 issue of the journal, Fertility and Sterility.
