Nonetheless, the ionizing radiation exposure during the examination could cause a cancer risk. Hence, this study aimed to evaluate the radiation dose and radiation-induced risk associated of whole-body PET/CT scan that includes the 18F-FDG tracers. For this retrospective study, 40 participants were studied, with an even number of males and females. The average age and weight of the participants were 53.77 ± 15.78 years and 66.59 ± 16.94 kg respectively, and they were administered 424.64 ± 121.19 MBq of 18F-FDG before the PET/CT commenced. The IDAC-Dose 2.1 program was employed to calculate the absorbed dose and effective dose in organs such as the bladder, brain, lung, kidneys, colon, red bone marrow (RBM), stomach, liver, and thyroid. The potential risks of cancer were evaluated using the lifetime attributable risk (LAR) via a 3rd order polynomial approach based on the information provided in the Biological Effects of Ionizing Radiation (BEIR) VII report. The effective dose was 20.1 ± 7.9 mSv, and the ratio of E to administered activity is 1.612 × 10-2 mSv/MBq, which is in line with the ICRP standard. The study found that the average incidence of cancer among men and women was 7 and 8 cases per 100,000 examinations, respectively, with effective dose between 3.2 mSv to 27.3 mSv. In summary, the risk of cancer associated with current whole-body 18F-FDG PET/CT examinations is low, but it is essential to mitigate radiation exposure during these examinations and utilize suitable techniques to prevent stochastic effects from low-dose radiation exposure.","PeriodicalId":506994,"journal":{"name":"Radioprotection","volume":"45 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141924331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To facilitate this, we developed a semi-automatic software employing Optical Character Recognition technology. This software analysed 1125 interventional procedures conducted between January 2021 and September 2023 at a large Brazilian hospital. The database includes the type of procedure, Air Kerma value, Kerma-Area Product, number of cineangiography images, and exposure duration, all realized on an Artis Zee® (Siemens Healthineers, Germany) C-arm. We established Local Diagnostic Reference Levels (LDRLs) and calculated Effective Dose values using the PCXMC 2.0 Monte Carlo simulation software. These calculations were based on data from the hospital and LDRLs determined in subsequent studies. The findings reveal that both the LDRLs and the calculated Effective Dose generally fall below the values reported in existing literature. This underscores the efficacy of our methodology in enhancing radioprotection and dose monitoring within the studied hemodynamics sector.","PeriodicalId":506994,"journal":{"name":"Radioprotection","volume":"29 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141925903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two hundred patients who underwent brain CT using automatic exposure control were enrolled. The radiation dose indices (volume CT dose index, CTDIvol; size-specific dose estimate, SSDE; dose length product, DLP) were compared with the head size indices (effective diameter, ED; water-equivalent diameter, WED) and body weight. The CTDIvol and SSDE correlated positively with the ED and WED. The correlations were higher for the WED than the ED and for the CTDIvol than the SSDE. Although the DLP also correlated positively with the ED and the WED, the correlations were lower than those for the CTDIvol and the SSDE. The CTDIvol and SSDE showed significant positive correlations with body weight, but the correlations were lower than those for the ED. In conclusion, the radiation dose indices in adult brain CT correlate with the head size indices. Consideration of the head size indices is recommended for radiation dose management in brain CT. The relationship between the radiation dose indices and body weight may be of some significance when the head size indices are not readily available.","PeriodicalId":506994,"journal":{"name":"Radioprotection","volume":"50 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141926837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its indispensability, the use of ionizing radiation in dental radiography entails inherent risks. Dental students, as future practitioners, bear the responsibility of acquiring thorough knowledge in radiation protection to ensure the safety of both patients and operators. \u0000Aim: This study seeks to evaluate the levels of awareness, knowledge, and approach regarding ionizing radiation among dental students enrolled in the dentistry program at Jazan university (JU). \u0000Material and Methods: A descriptive, cross-sectional survey was carried out involving 82 dental students, with a participant distribution of 63 males (77%) and 19 females (23%) across different academic years. The survey utilized a structured questionnaire designed to assess awareness regarding deterministic and stochastic effects of ionizing radiation, as well as various aspects of radiation protection practices. Demographic factors, including gender and academic year, were scrutinized for their potential impact on radiation protection awareness. The collected data underwent statistical analysis using chi-square tests implemented in SPSS to explore any significant associations. \u0000Results: The study included 82 dental students with varying age distributions. Age-wise, 39% fell within the 21-23 years range, 31% were between 18-20 years, 24% ranged from 24 to 26 years, and 6% were older than 26 years. Participants were distributed across different academic years, with the largest group being fourth-year students (25%), followed by fifth-year students (15%). Female students exhibited higher awareness of the National Council on Radiation Protection (NCRP) and International Commission on Radiological Protection (ICRP) recommendations, and the practice of standing behind lead barriers during exposure. \u0000 \u0000 \u0000Conclusion: \u0000This study underscores the overall elevated awareness and knowledge regarding radiation protection among dental students. Nevertheless, distinct gender-related variations in specific facets of awareness were identified, underscoring the necessity for targeted educational interventions.
