Transvaginal ultrasound-guided saline infusion sonohysterography (SHG) is a relatively new technique for evaluation of the uterine cavity. As new studies declare the clinical usefulness of this technique, SHG may quickly become part of the routine ultrasound evaluation of the female pelvis. In this article, the SHG procedure is described and normal findings are discussed. Common endometrial pathological findings such as atrophy, polyps, fibroids, hyperplasia, and carcinoma are reviewed. The newly touted roles of SHG for screening patients on long-term tamoxifen therapy and for evaluating patients with infertility are introduced. Finally, we present a practical ultrasound-based flow chart for the workup of menopausal and perimenopausal patients with abnormal uterine bleeding.
