  • Fallopian tubes are on either side of the uterus attached to it near cornua and the other end is free located adjacent to ovaries.
  • It has interstitial, isthmic, ampullary and fimbrial parts. Interstitial end is attached to the uterus and fimbrial end is free.
  • Fallopian tubes vary in length from 7-12cm.
  • Normal tubes are usually not visualised by ultrasound.
  • If there is a tubal pathology like hydrosalpinx in which tubes are blocked with accumulation of fluid in it, they can be visualised on USG.
  • Cervix as seen on USG with a clear layer of mucus in the cervical canal is a favourable sign reflecting good level of oestrogen production.
  • Presence of free fluid in the pelvic cavity also can make the tubes visible.
  • As tubes are not normally seen on ultrasound hysterosalpingography (HSG) or Hystrerosalpingo contrast sonography (HyCoSy) is used to know the tubal patency.
  • Tubes are assessed during basic USG scan on 2 day or 9 day of menstrual cycle.
  • Few cysts like Paraovarian, paratubal cysts (cysts of morgagni) and those adjacent to uterus, vagina & superior to hymen like Gartner’s duct cyst can be seen on routine scan in some patients.
