Sonohysterogram (SIS or SHG)

A sonohysterogram (SHG), also called a saline infusion sonogram (SIS) is a diagnostic procedure performed in our office to evaluate the uterus by injecting saline into the uterine cavity while performing an ultrasound. The saline helps create a clearer image of the uterine lining and structure, allowing doctors to detect abnormalities such as polyps, fibroids, or scarring. This non-invasive procedure is commonly used to investigate causes of abnormal bleeding, infertility, or recurrent miscarriages and is typically done with minimal discomfort.
