One study of prostatic artery embolization found radiation exposure of 176.5 Gy/cm2. (1) This is roughly equivalent to ~5–10 standard abdominal/pelvic CT scans (more if using ultra-low dose scanners), 586 chest X-rays, 4.4 barium enemas or 8.8 voiding cysto-urethrograms. (3) To put that in perspective, a study of 14,150 patients who had Abdominal Endovascular Aneurysm Repair (EVAR) found an increased risk of abdominal cancer with 18% eventually succumbing to cancer. (2) The mean radiation exposure for EVAR is 79.58 Gy/cm2, approximately 1/2 the radiation exposure of PAE. (4)
