Sonohysterography

Sonohysterography is a valuable and simple, minimally invasive ultrasound procedure that may be used to evaluate the endometrium."n"n SHG augments the traditional TVS examination by distending the endometrial canal with saline, which allows each individual layer of endometrial lining to be evaluated separately. The single-layer evaluation made possible by SHG significantly improves detection and the characterization of focal and diffuse endometrial processes over that of TVS alone The technique involves placement of a catheter into the endometrial canal with subsequent instillation of sterile saline solution under ultrasound guidance.
