Purpose  To evaluate the effect of cone-beam computed tomography (CBCT) on radiation exposure, procedure time, and contrast media (CM) use in prostatic artery embolization (PAE).    Materials and Methods  Seventy-eight patients were enrolled in this retrospective, single-center study. All patients received PAE without (group A;  n  = 39) or with (group B;  n  = 39) CBCT. Total dose-area product (DAP total ; Gycm 2 ), total entrance skin dose (ESD total ; mGy), and total effective dose (ED total ; mSv) were primary outcomes. Number of digital subtraction angiography (DSA) series, CM use, fluoroscopy time, and procedure time were secondary outcomes. PAE in group A was performed by a single radiologist with 15 years experience, PAE in group B was conducted by four radiologists with 4 to 6 years experience.    Results  For groups A vs. B, respectively, median (IQR): DAP total  236.94 (186.7) vs. 281.20 (214.47) Gycm 2 ( p  = 0.345); ED total  25.82 (20.35) vs. 39.84 (23.75) mSv ( p  =  < 0.001); ESD total  2833 (2278) vs. 2563 (3040) mGy( p  = 0.818); number of DSA series 25 (15) vs. 23 (10)( p  = 0.164); CM use 65 (30) vs. 114 (40) mL( p  =  < 0.001); fluoroscopy time 23 (20) vs. 28 (25) min( p  = 0.265), and procedure time 70 (40) vs.120 (40) min( p  =  < 0.001). Bilateral PAE was achieved in 33/39 (84.6%) group A and 32/39 (82.05%) group B( p  = 0.761), all other patients received unilateral PAE. There were no significant differences between clinical parameters and origins of the prostatic arteries (PA) ( p  = 0.206–1.00).    Conclusion  Operators with extensive expertise on PAE may not benefit from addition of CBCT to DSA runs, whereas for operators with less expertise, CBCT when used alongside with DSA runs increased the overall radiation exposure.
