Sonohysterography is a medical imaging technique used to examine the inside of the uterus. It involves the injection of a sterile saline solution into the uterine cavity through the cervix. This fluid helps to create a clearer picture during an ultrasound, allowing doctors to identify abnormalities such as fibroids, polyps, or other uterine conditions. The procedure is typically performed in a doctor's office and takes about 30 minutes. Patients may experience mild discomfort, but it is generally well-tolerated. Sonohysterography is a valuable tool for evaluating uterine health and guiding treatment options.
