New Ultrasound Technology for Early Detection of Preterm Birth Risk

New Ultrasound Technology for Early Detection of Preterm Birth Risk

Researchers have developed a cutting-edge ultrasound technique that can identify “microstructural” changes in a woman’s cervix, which could indicate a higher risk for preterm birth. The groundbreaking scans can be performed as early as week 23 of pregnancy and have the potential to help assess the risk of preterm delivery, even among first-time mothers.

Traditionally, clinicians have relied on signs and symptoms of preterm birth, such as a ruptured membrane, to make decisions. However, this new technique provides a more proactive approach by analyzing the tissue itself rather than relying solely on symptoms. The ultrasound scans, known as quantitative ultrasound, not only capture visual images but also utilize radiofrequency data to evaluate the density of different tissues.

The idea for this innovative approach was conceived by study lead author Barbara McFarlin, a professor emeritus of nursing at the University of Illinois Chicago, during her time as a graduate student and midwife. She noticed distinct differences in the cervix of women who later experienced premature delivery and recognized the untapped potential of this observation.

To validate the efficacy of the technique, McFarlin and her team studied the pregnancies of 429 women who gave birth without induction. By using quantitative ultrasound to detect microstructural changes in cervical tissue, they were able to accurately predict which first-time mothers would deliver prematurely. The combination of ultrasound data and prior history of premature birth proved to be even more effective in predicting subsequent premature delivery.

The implications of this ultrasound test extend beyond early detection. If doctors can identify a higher likelihood of early delivery at 23 weeks, they can arrange more frequent appointments to monitor the health of the fetus and potentially take preventive measures. This groundbreaking research opens up possibilities for further investigation and intervention to prevent or delay preterm birth.

The study, published in the American Journal of Obstetrics & Gynecology, marks a significant advancement in obstetric practices. By harnessing the power of quantitative ultrasound, healthcare professionals can now potentially identify preterm birth risks earlier and provide targeted care to reduce complications associated with premature delivery.
