3D Ultrasound: what is its use in reproductive medicine?


Ultrasonography is a key diagnostic test in pregnancy, which allows evaluating the structures and anatomy of the fetus, as well as the condition of the woman. But ultrasound in reproductive medicine, especially three-dimensional, is also key to conducting a basic study of a woman’s reproductive organs. We spoke with Dr. Cristina Ros about the advances in 3D ultrasound in reproductive medicine. She is a gynecologist specialized in imaging techniques in assisted reproduction and a consultant physician at FIVclínic.

Dra Cristina Ros was, during her training period, resident doctor of Obstetrics and Gynecology at the Hospital Clínic de Barcelona. There she lived the application of technological advances in ultrasound imaging in the study of the pregnant woman’s fetal morphology. Later, interested in gynecological ultrasound, she learned how to apply three-dimensional ultrasound. Throughout her career, she experienced increased resolution of images in the field of Gynecology and Reproduction. After several training stays in Italy, Poland and Brazil, with expert sonographers, she transferred this new vision to her daily practice at the Clinic.

What does 3D ultrasound provide in reproductive medicine?

The first advance that allowed the use of 3D ultrasound is to replace diagnostic hysteroscopy as a basic study of the uterine cavity with transvaginal 3-dimensional (3D) ultrasound. “The development of the three-dimensional transvaginal ultrasound gives us the assessment, not only of two planes, but also of a third plane of the internal genitalia: the coronal plane. It is the plan of choice to identify and classify uterine malformations. Among them, uterine septa, bicornuate uterus or unicorn uterus, which would go unnoticed in the two-dimensional study and have relevant reproductive repercussions, ”says Dr. Ros.

Furthermore, 3D ultrasound in reproductive medicine also allows a more precise assessment of the possible printing of a myoma on the endometrial cavity. Also its size or volume. And, in the case of adhesions, scars or scrapes, the three-dimensional ultrasound allows the visualization of the exact size of the uterine cavity. This allows for a better evaluation of any area of ​​possible distortion.

“Today, we indicate the performance of a hysteroscopy only in the case of identifying or suspecting endocavitary pathology when performing 3D ultrasound, a much more comfortable technique for the patient,” adds Ros.

3D technology is also applicable to the finding of ovarian tumors or tubal pathology. And it offers the visualization of a third plane and the possibility of offline analysis of the volume obtained.

Should a 3D ultrasound be performed before a reproduction treatment?

“Yes, three-dimensional ultrasound is a useful test for evaluating the uterine cavity prior to performing assisted reproduction treatment. Also as a more detailed examination of pathology of the ovaries or fallopian tubes”, she explains.

“My activity applied to the world of reproduction is gratifying and motivating, since it helps to better approach the woman who wants a pregnancy,” explains Ros.
