Bracco Imaging Receives Regulatory Approval in China for SonoVue® in the Assessment of Fallopian Tube Patency

New indication of SonoVue^® supports non-invasive assessment of female infertility through contrast-enhanced ultrasound in China

MILAN, Aug. 6, 2025 /PRNewswire/ -- Bracco Imaging, a global leader in diagnostic imaging, today announced that its ultrasound contrast agent SonoVue^® has been approved by the China's National Medical Products Administration (NMPA) for use in hysterosalpingo contrast sonography (HyCoSy).

HyCoSy is a contrast-enhanced ultrasound (CEUS) procedure that helps identifying potential causes of female infertility related to blockage of the fallopian tubes or uterine abnormalities with a high level of diagnostic accuracy (1,2). Fallopian tube conditions, such as blockages, scarring, or other damage, are a leading cause of infertility, contributing to approximately 25–35 percent of cases of infertility among women in China (3).

This regulatory approval represents an important milestone in the management of infertility because, unlike laparoscopic assessment of tubal patency with use of a dye, HyCoSy is a non-invasive procedure, and, unlike traditional X-ray hysterosalpingography, HyCosy does not expose to radiation the genital tract of women in their reproductive years (4-6).

"The NMPA approval of SonoVue^® use with HyCoSy marks an important step in expanding access to non-invasive, radiation-free detection of tubal issues and uterine problems that often cause infertility in women," said Alberto Spinazzi, Chief Medical and Regulatory Officer, Bracco Group. "We strive to provide healthcare professionals in China with solutions that advance standards of care, reflecting our commitment to advancing diagnostic precision and improving the patient experience through contrast-enhanced ultrasound."

"We are proud to support China's healthcare priorities through solutions like SonoVue^® that may help address important diagnostic needs," said Valtero Canepa, Head of APAC, Bracco Imaging. "This new indication advances Bracco's role in delivering meaningful innovation in support of the Healthy China 2030 initiative, which prioritizes earlier detection, clinical precision, and broader access to reproductive health services."

The high diagnostic performance of HyCoSy with SonoVue^® has been confirmed by a recent systematic review and meta-analysis of 24 clinical studies (total of 1358 women with infertility and 2661 fallopian tubes). Using laparoscopic chromotubation dye test as the standard of truth for the assessment of fallopian tube patency, the pooled estimates of sensitivity, specificity, and accuracy of HyCoSy with SonoVue^® were 93%, 90%, and 96%, respectively (1). 

Backed by over 20 years of clinical use, SonoVue^® is the ultrasound contrast agent with the largest number of approved indications in the largest number of countries worldwide. The newly approved HyCoSy indication reinforces Bracco Imaging's commitment to expanding non-invasive, high-quality diagnostic tools aligned with evolving clinical standards and national health objectives in China and beyond.
