Purpose: To evaluate the cumulative radiation dose for diagnosis and treatment with diagnostic radiology tools for patients with hepatocellular carcinoma. Materials and Methods: Cumulative radiation dose of 98 patients with hepatocellular carcinoma were examined by diagnostic CT, CT for follow-up, once or repeated transarterial chemoembolization (TACE), and X-ray examinations. Thus, we calculated the total cumulative effective doses per patient. Results: The mean follow-up periods were 85 (51-102) weeks. A total of 565 CT scans, 262 TACEs, and 1679 X-ray examinations were enrolled. Cumulative effective dose values per person of 91.4 ± 50.6 (8.4-244.7) mSv, 49.2 ± 44.7 (5.3-247.6) mSv, and 3.6 ± 4.7 (0.02-22.04) mSv were measured for CT, TACE, and X-ray examinations. Total cumulative effective dose values per person were measured as 144.2 ± 87.4 (15.4-513.5) mSv. Conclusion: The patient who underwent TACE are exposed to pretty high dose radiations, thus, significant efforts to reduce the radiation dose are necessary.
