Background: Transarterial Radioembolization (TARE) is an effective treatment option for both primary and secondary liver malignancies. However, challenging anatomical conditions can lead to prolonged fluoroscopy times (FT), elevated doses of periprocedural X-radiation (DAP), increased use contrast agents (CAs). In this study, we examined the influence our radiologists’ experience choice microspheres on X-ray exposure CA in TARE. Material Methods: Datasets comprising 161 TARE 164 preprocedural evaluation angiographies (TARE-EVA) were analyzed. Our study focused assessing DAP, FT, concerning microsphere types, radiologist’s experience, whether same radiologist performed TARE-EVA actual Results: TARE, resin resulted significantly higher FT compared glass (14.3 ± 1.6 min vs. 10.6 1.1 43 2.2 mL 33.6 2.1 mL, p < 0.05), with no notable differences DAP (p = 0.13). Experienced radiologists demonstrated reduced FT/DAP, a 19% decrease 53% during angiography 0.05) 49% reduction statistical FT. Performing under led 43% 25% 0.05, respectively). Conclusions: To mitigate exposure, it advisable undergo thorough training, and, ideally, should conduct TARE-EVA. While spheres may intraarterial CA, does not impact exposure.
