Abstract Objective To evaluate the X-ray radiation of patients during uterine artery embolization (UAE) for leiomyomas.Methods Radiation dose was measured in 90 patients who underwent UAE for leiomyomas.Measurements were obtained by a dosimeters system (Diamentor K1 and Diamentor ED) equipped in DSA setting Angiostar-Plus (Siemens, Germany), dose-area product (DAP) and entrance surface dose (ESD) were recorded on line, effect dose (ED) was estimated by Monte-Carlo conversion coefficient from DAP.Results The mean fluoroscopic time was 28.60±23.73 minutes, and the mean number of angiographic exposures was 87±38.The mean DAP dose was (6 178±3 802) cGy cm2, and the mean ESD was 378±245) mGy, ED was (9.89±6.08) mSv.The contribution of pulsed fluoroscopy (PF) dose to the total DAP (34.05%±10.65%) was smaller than that of radiography (R) (65.94%±10.65%), and the contribution of PF for total ESD (61.09%±12.88%) was bigger than that of R (65.94%±10.65%).Conclusion The leiomyoma patient suffered a large dose X-ray exposure from a UAE procedure.
