Although CBCT offers great advantages in terms of improving comprehension of complex angioarchitectures and guiding therapeutic decisions, its additional degree of radiation exposure has also aroused considerable concern. In this study, we aimed to assess radiation exposure and its influential factors in patients undergoing CBCT scans of the head and abdomen during interventional procedures. A total of 752 patients were included in this retrospective study. Dose area product (DAP) and reference air kerma (RAK) were used as measures of patient dose. The results showed that the median values of DAP were 53.8 (50.5\u201364.4) Gy\u22c5cm2 for head CBCT and 47.4 (39.6\u201354.3) Gy\u22c5cm2 for that of the abdomen. Male gender and body mass index (BMI) were characterized by increased DAP and RAK values in both head and abdominal CBCT scans. Larger FOV size was associated with a higher DAP but a lower RAK value, especially in head CBCT scans. Exposure parameters under automatic exposure control (AEC) also varied according to patient BMI and gender. In conclusion, the patients received slightly higher radiation doses from head CBCT scans than from those applied to the abdomen. BMI, gender, and FOV size were the key factors that influenced the radiation dose administered to the patients during CBCT scans. Our results may help to define and minimize patients\u2019 exposure to radiation.<\/jats:p>","DOI":"10.3390\/tomography10030025","type":"journal-article","created":{"date-parts":[[2024,2,26]],"date-time":"2024-02-26T11:31:21Z","timestamp":1708947081000},"page":"320-330","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Evaluation of Radiation Exposure and Influential Factors in Cone-Beam Computed Tomography (CBCT) of the Head and Abdomen during Interventional Procedures"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1795-1262","authenticated-orcid":false,"given":"Mingming","family":"Li","sequence":"first","affiliation":[{"name":"Department of Interventional Radiology, The First Affiliated Hospital of Soochow University, No. 188 Shizi Road, Suzhou 215006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiwei","family":"Qu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Radiation Medicine and Protection, School for Radiological and Interdisciplinary Sciences (RAD-X) and Collaborative Innovation Center of Radiation Medicine of Jiangsu Higher Education Institutions, Soochow University, Suzhou 215123, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology, The First Affiliated Hospital of Soochow University, No. 188 Shizi Road, Suzhou 215006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Binyan","family":"Zhong","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology, The First Affiliated Hospital of Soochow University, No. 188 Shizi Road, Suzhou 215006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhi","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology, The First Affiliated Hospital of Soochow University, No. 188 Shizi Road, Suzhou 215006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhengyu","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology, The First Affiliated Hospital of Soochow University, No. 188 Shizi Road, Suzhou 215006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guanyin","family":"Ni","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology, The First Affiliated Hospital of Soochow University, No. 188 Shizi Road, Suzhou 215006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caifang","family":"Ni","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology, The First Affiliated Hospital of Soochow University, No. 188 Shizi Road, Suzhou 215006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"521","DOI":"10.1007\/s11547-014-0429-5","article-title":"C-arm cone-beam computed tomography in interventional oncology: Technical aspects and clinical applications","volume":"119","author":"Floridi","year":"2014","journal-title":"Radiol.
