The aim of this study was to evaluate the efficiency of a new composition of a shielding material with minimal impact on image quality. Materials and methods: Different breast shields were manufactured with varying weight percentages of copper and BaSO4. Thermoluminescent dosimeters (TLD) and thorax phantoms were used to assess the radiation shielding effectiveness. Image quality, in terms of noise and CT number accuracy, was quantitatively evaluated on a CTDI phantom. Additionally, a controlled trial with 60 female participants was conducted to further assess image quality and select the best breast radiation shield. Results: The results indicated that the different shield compositions reduced the surface dose by 14.17-51.69%. The shield with a composition of 90% Cu-10% BaSO4 and 50% Cu-50% BaSO4 had the lowest noise, while the 100% bismuth shield had the highest noise. Importantly, the 50% Cu-50% BaSO4 shield did not cause artifacts in the thoracic CT images. Conclusion: By using the 50% Cu-50% BaSO4 shield, a significant dose reduction was achieved while maintaining appropriate image quality, making it suitable for clinical applications.","PeriodicalId":21009,"journal":{"name":"Radioprotection","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141652852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advancements in digital radiography, mammography, fluoroscopy, and interventional radiology have reshaped imaging techniques. Traditional methods, augmented by digital tools and algorithms, optimize imaging while minimizing radiation exposure. Innovations such as ultra-low-dose imaging in mammography aim to enhance cancer detection with reduced radiation. Optimization in fluoroscopy and interventional radiology involves a nuanced approach, considering both equipment protocols and operator behavior. Collaboration between medical physicists and optimization teams aligns protocols with equipment functionality. ISO-defined quality management principles guide the establishment of quality in radiology departments through components like quality control and assurance. Dosimetry monitors equipment performance and estimates individualized radiation risks, ensuring patient safety. Performance indicators help in assessing departmental performance, with medical physicists driving their development and monitoring. Collaborative initiatives and emerging technologies, including artificial intelligence and theranostics, underscore the ongoing journey of dose optimization in radiology. These strategies will shape the future of radiological imaging, enabling personalized patient care and advancing our understanding of health and disease.","PeriodicalId":21009,"journal":{"name":"Radioprotection","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141837191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic quantitative content analysis of online resources was conducted from November 27 to December 8, 2023. The selection criteria were websites in Japanese related to nuclear disaster prevention and aimed at the general public. The PEMAT-P, jReadability, Journal of the American Medical Association benchmark criteria, and Global Quality Scale were used to evaluate each web page. The number of respondents who scored 70 or higher on the PEMAT-P was 71 (61.2%) for Understandability and 57 (49.1%) for Actionability. Regarding the difficulty level of the texts by jReadability, \"Difficult\" was the most frequent response with 82 responses (70.7%).

Key metrics, including effective diameter (Deff) and water-equivalent diameter (Dw), play pivotal roles in characterizing patient size. However, a notable gap exists in delineating the specific relationships between age and head patient size (Deff and Dw) for pediatric patients in Morocco. The primary objective of this study was to establish these critical associations between patient age and head patient size (Deff and Dw), providing a foundation for calculating size-specific dose estimates (SSDE) in pediatric head CT examinations. A retrospective analysis of data from 134 pediatric patients, aged 0-13 years, comprising 71 males and 63 females who underwent head CT scans, was conducted. Utilizing the Radiant DICOM Viewer, patient sizes were measured in terms of both lateral and anterior-posterior dimensions for Deff and Dw calculations based on CT images in DICOM format. Our analysis revealed robust correlations between patient size (Deff and Dw) and the patient's age, with R2 values ranging from 0.65 to 0.86. Notably, larger Dw values were consistently observed compared to Deff. For male patients, Deff measurements ranged from 9.02 to 18.77 cm, with Dw values spanning 9.83 to 20.16 cm. Female patients exhibited Deff values ranging from 8.77 to 17.41 cm and Dw values ranging from 8.92 to 18.37 cm. These findings shed light on the crucial relationship between age and patient size, facilitating more precise dose calculations.","PeriodicalId":21009,"journal":{"name":"Radioprotection","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140977484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the effect of implementing national diagnostic reference levels (NDRLs) for radiation dose optimization in 1,991 adult chest CT scans at a major Saudi hospital. Data was analyzed before and after NDRL implementation, with 21.5% of scans using contrast and 78.5% without. Before implementation, 11.1% used contrast and 36.7% did not; after implementation, 10.4% used contrast and 41.7% did not. The majority (83.5%) of scans passed NDRL criteria [CTDIvol and DLP are set at 12 (mGy) and 430 (mGy·cm)], with higher pass rates for contrast (91.8%) versus non-contrast (81.5%) scans. Effective dose (ED) was compared before and after NDRL implementation. For non-contrast scans, ED declined 2.43% from 12.37±5.25 mSv to 12.07±4.99 mSv after implementation (non-significant, p>0.05). For contrast scans, ED declined more substantially, 6.77% from 9.6±4.61 mSv to 8.95±4.44 mSv (non-significant, p>0.05). The findings highlight higher NDRL compliance in procedures with contrast and show areas for dose optimization improvement in procedures without contrast. Results suggest NDRLs provide guidance for optimizing radiation dose, but other factors like patient characteristics, protocol settings, and quality assurance programs should also be considered to ensure doses are as low as reasonably achievable (ALARA) without compromising diagnostic quality. Regular monitoring and review of CT protocols is recommended to avoid unintended consequences of dose reduction. Continued optimization is encouraged to reduce dose while ensuring quality.","PeriodicalId":21009,"journal":{"name":"Radioprotection","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140232887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
