title: Patient radiation dose associated with uterine artery embolization.
abstract: OBJECTIVE
  To evaluate the estimated absorbed radiation doses to the ovaries and skin entrance during uterine artery embolization (UAE) for leiomyomas.
  
  
  METHODS
  Radiation dose was measured in 20 patients who underwent UAE for leiomyomas. Measurements were obtained by placing lithium fluoride dosimeters both into the posterior fornix of the vagina and on the skin at the beam entrance site. Patient doses were obtained with thermoluminescent dosimeters.
  
  
  RESULTS
  The mean fluoroscopic time was 21.89 minutes, and the mean number of angiographic exposures was 44. The mean estimated absorbed ovarian dose was 22.34 cGy, and the mean absorbed skin dose was 162.32 cGy. These values compare to published values for the assessed absorbed ovarian dose during hysterosalpingography (0.04-0.55 cGy), fallopian tube recanalization (0.2-2.75 cGy), computed tomography of the trunk (0.1-1.9 cGy), and pelvic irradiation for Hodgkin disease (263-3,500 cGy).
  
  
  CONCLUSIONS
  The estimated absorbed ovarian dose during UAE is greater than that during common fluoroscopic procedures. On the basis of the known risks of pelvic irradiation for Hodgkin disease, the dose associated with UAE is unlikely to result in acute or long-term radiation injury to the patient or to a measurable increase in the genetic risk to the patient's future children.
