Background: This study aimed to estimate occupational doses and patient peak skin doses (PSDs) during interventional radiology procedures. Materials and Methods: We examined data from brain embolization (n = 30), hepatic chemoembolization (n = 50), and uterine embolization (n = 12). The PSDs were measured using radiochromic film around the patient' s head (group 1) or abdominal/pelvic region (group 2). Acquisition technical data and kerma-area products (KAP) were also recorded. Occupational doses were measured using Instadose TM dosimeters near the left eye region (LER), chest, and left ankle. Results and Discussion: The third quartile (median) KAP values were 408.1 (235.3) Gy• cm 2 for group 1 and 584.4 (449.4) Gy• cm 2 for group 2. The average PSDs were greatest during vascular procedures, reaching 1,004.4 (786.4) mGy, and the highest PSD was 2,352.6 mGy (during hepatic chemoembolization). The third quartile (median) occupational doses were 0.35 (0.21) mSv at the LER, 0.25 (0.15) mSv at the chest, and 1.47 (0.64) mSv at the left ankle. Occupational doses at the LER were higher than at the chest, which highlights the importance of protective glasses and suspended shields. The occupational doses at the ankle region were also high, which highlights the importance of using a lead-lined curtain attached to the table. Conclusion: The results indicate that physicians can reach, for eye region, the weekly occupational dose limit after around 15 procedures, even when using proper protection. The average PSD values were below the threshold for tissue reactions, although the complexity of these procedures emphasises the importance of considering related risks.

Liver malignancies are the sixth leading cause of cancer worldwide, whereas hepatocellular carcinoma (HCC) is the most frequent histological type of liver cancer. Extrahepatic metastasis, which rarely involves the mediastinum, is associated with poor prognosis. An 80-year-old male presenting with mild diffuse abdominal pain for 4 months, associated with hyporexia, increased abdominal volume, dry cough, and loss of 4 kg in 1 month, sought medical assistance due to hemoptysis and chest pain. Tomographic study revealed HCC with mediastinal metastasis, after which sorafenib therapy was started. Disease progressed to death 4 months after the start of the treatment.
