About Sono HSG

The most commonly performed procedure to determine fallopian tube patency (open or blocked) is a fluoroscopic hysterosalpingogram (HSG).  This method consists of infusion or filling of the entire uterine cavity with radiopaque (x-ray) dye allowing for fluoroscopic imaging of each fallopian tube and the uterine cavity.  The limitations of this procedure include that it must be performed by a radiologist or someone trained in radiographic imaging, radiation exposure, risk of allergic reactions to the radiopaque dye, and is performed in a medical imaging center. 

It is universally recognized that an office-based method of assessing tubal patency would be a significant advancement.  A sono-hysterosalpingogram (Sono HSG) may be an ideal screening tool as it utilizes existing ultrasound equipment in a gynecologist's office while avoiding radiation exposure.

A successful Sono HSG procedure is dependent on

1. Continuous and reliable delivery of saline and air as contrast
2. Ability to sonographically locate the contrast traveling in the fallopian tubes
