The Sono HSG Procedure

Sono HSG is a safe, simple, and effective ultrasound alternative to the X-ray HSG.

The FemVue® Saline-Air device is used to introduce a consistent mixture of saline and air contrast in a controlled fashion for the tubal evaluation portion of the Sono HSG. The bright echoes of the air bubbles can be seen flowing into and through each fallopian tube, providing physicians an effective contrast to make a tubal patency determination.

Cost-effective, convenient, and Proven

FemVue delivers a consistent pattern of saline and air, appearing as bubbles under ultrasound, to evaluate tubal patency.

Large meta-analysis showed diagnostic accuracy with Sono HSG and comparability with fluoroscopic HSG with no significant difference in performance of the two tests.*

A complete in-office fertility assessment with existing ultrasound equipment, expands practice services and saves patient time and expense.
