Sonohysterography

Sonohysterography can distinguish focal from diffuse pathology reliably and has become a crucial imaging test in the triage of PMB and in premenopausal patients with dysfunctional uterine bleeding or infertility. Polyps and submucosal fibroids are the most common focal findings during SHG. In postmenopausal patients, detection and accurate localization of findings, rather than lesion characterization, are the primary goals of the procedure. Most, if not all, focal lesions in this patient population require tissue diagnosis, even when the imaging features suggest benign lesions.
