Ultrasound is safe, noninvasive and does not use ionizing radiation.  A transvaginal ultrasound is used by doctors to examine female reproductive organs -  uterus, fallopian tubes, ovaries, cervix, and vagina. A transvaginal ultrasound helps diagnose multiple conditions, including:

• cancer of the reproductive organs
• routine pregnancy
• cysts
• fibroids
• pelvic infection
• ectopic pregnancy
• miscarriage
• placenta previa (a low-lying placenta during pregnancy that may warrant medical intervention)
