What is OB/GYN Radiology?

Obstetrics and Gynegological imaging is a subcategory of radiology that focuses on the female reproductive system. These imaging tests and scans are commonly used to confirm pregnancy, visualize opacification of fallopian tubes, blockages or disruption of the fertility system, to detect cancer, or to verify placement of birth control devices (IUDs).

Due to the harmful effects of radiation on the female reproductive system, ultrasonography is the most utilized and relied on imaging technique in this subcategory. Exposure to stronger radiation can sterilize a woman's reproductive system, and damage a growing fetus.

Other gynecological radiology tests include: 

  • Hysterosalpingography (HSG) - used to see whether the fallopian tubes are patent (open) and if the inside of the uterus (uterine cavity) is normal.
  • Sonosalpingography (SSG), also known as Sion test,  used for evaluating patency of fallopian tubes.
  • Transvaginal ultrasonography - uses ultrasound waves go across the vaginal wall to visualize organs within the pelvic cavity.
