There are many methods which are used as adjuvant in rehabilitation of post-burn contracture patients. The low-level laser therapy (LLLT) is one of the methods that can be used as an adjuvant in rehabilitation of joint stiffness following burns and but with very few data available from India. In this article we share our experience of using LLLT for functional rehabilitation of a patient with joint stiffness following postburn contracture. Materials and Methods This study was conducted in a burns centre in a tertiary care institute in South India. Informed consent and departmental ethical committee clearance were obtained prior to study. The subject was a young boy with no known co-morbidities with stiffness of metacarpophalangeal and interphalangeal joint of index and middle finger of right hand. Patient was treated with contracture release with full thickness skin graft. The patient received low-level laser therapy to induce collagenolysis and to increase the movement of the joints. Each joint received laser therapy for duration of 125-second every time for 15-minutes for 2 sessions in a span of 4-days. Result LLLT has been found to be useful in early rehabilitation of post-burn contracture patients with joint stiffness. No side effects were observed during the study. Conclusion The LLLT is an effective, safe, and non-invasive adjuvant in functional rehabilitation of our patient with joint stiffness following post-burn contracture. We suggest further study including multiple subjects and a control group for validation of the result.","PeriodicalId":91603,"journal":{"name":"Radiology - open journal","volume":"77 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73310320","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}

{"title":"Current State of Gonadal Shielding in Medical Imaging: A Review","authors":"Julie Ho, E. Seeram, Edel Doyle, Simone Roberts, John Mc Inerney","doi":"10.17140/roj-6-137","DOIUrl":"https://doi.org/10.17140/roj-6-137","url":null,"abstract":"Introduction In recent times the benefits of using gonadal shielding have been brought into question. Several professional bodies have released positional statements in support of ceasing the use of gonadal shields. However, in Australia the regulatory authority for radiation has not commented to date. This literature review aims to explore the risks and benefits of using lead protection and to establish the current state of the use of gonadal shields in clinical practice. Methods A search of the literature was conducted using online databases under the subject “Medical Imaging and Radiation Sciences”. Key terms and phrases included “lead protection”, “plain film imaging”, “lead shielding”, “gonadal shielding”, “X-ray”, “radiography”, “pelvic radiography”, “radiation protection”, “methods”, “education” and “gonadal shielding”. Articles pertaining to radiation therapy, literature reviews and those not in English were excluded. Results and Discussion Gonad shields are often poorly used despite agreement of what constitutes accurate and inaccurate shielding. Inaccurate shielding relates to both inappropriate size and inaccurate positioning of shields. Retrospective studies demonstrated a higher incidence of inaccurate gonadal shield placement in females compared to males. Inaccurate shielding had implications for patients such as obscuration of important anatomy and pathology and increased radiation dose if repeat X-rays were required to correct positioning errors. Shield design innovation was identified as a future area of research that could assist with overcoming these errors. Where gonad shielding was found to be of benefit in patients with conditions that require regular follow-up imaging. This is especially important in conditions affecting children and adolescents who have increased radiosensitivity and longer life expectancy. Conclusion Studies have demonstrated high incidence of inaccurately positioned gonad shields for female patients, which leads to repeated X-ray images and increased dose to patients. However, shielding has been shown to be beneficial for patients requiring frequent X-ray examinations to reduce cumulative radiation dose. Establishing a standardised protocol regarding the application of gonadal shields, supported by regulatory agencies, is imperative.","PeriodicalId":91603,"journal":{"name":"Radiology - open journal","volume":"68 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83449483","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}

The use of lead shielding in protecting staff in low-dose settings, such as plain film and mobile radiography, is therefore an important aspect of practice to be reviewed. The objective of this review is to evaluate the use of lead shielding in protecting staff in plain film and mobile radiography, while also exploring the evolution of occupational doses and perceptions of lead protection. While literature is limited on the use of lead protection for staff in mobile settings, lead protection has been shown to reduce staff and adjacent patient dose from scatter. Furthermore, despite the increased frequency of medical imaging procedures in contemporary radiography, the occupational doses of medical radiation workers have reduced over time. With literature demonstrating gaps in current understandings of radiobiological mechanisms at low doses, the linear no-threshold model utilised to estimate radiation risk and develop protection standards cannot be rejected. Thus, this review finds the need for further research to be undertaken to improve risk estimates at low doses in larger cohorts of medical radiation workers, for the demonstration of long-term effects from occupational exposure, prior to ceasing staff lead protection.","PeriodicalId":91603,"journal":{"name":"Radiology - open journal","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88767060","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}

Waris","doi":"10.17140/ROJ-4-130","DOIUrl":"https://doi.org/10.17140/ROJ-4-130","url":null,"abstract":"Purpose This study analysed the sensitivity of the field size from variations in the target volume dimensions, depth, and position. The variations in the target volume analysis were used to determine the width of the field size. Thus, the quality control of the radiation beam can be obtained. Materials and Methods The computed tomography (CT) image of the IBA Dose 1 type of water phantom consists of 350 slices. Variations in the dimension of the target volume were modelled in 10×10×10 cm3, 10×12×10 cm3 , 10.2×10×10.2 cm3, and 15×15×15 cm3. Beam parameters use one beam of irradiation on the central axis 0°, 6 MV energy, 100 cm source-skin distance (SSD), beamlet delta x, and y set to 0.1 cm. Dose distribution in the form of the XZ isodose curve and dose profile was used to observe the field size. Results In this study, the isodose curve was successfully displayed in the XZ isodose curve. The field size’s sensitivity has been successfully reviewed from variations of the target volume, depth, and position. The target X and Z direction analysis is used in determining the width and length of the field size. Conclusion The analysis related to the field size sensitivity study was obtained from a relatively valid calculation. The field size was evaluated with variations in depth of 1.5 cm, 5 cm, 10 cm, and variations in positions of 10 cm, 12 cm, 14 cm, 18 cm, and 20 cm. This study will be used as a reference to validate the distribution of computational environment for radiotherapy research (CERR) dose in the future. Thus, the accuracy of the dose calculation can be obtained.","PeriodicalId":91603,"journal":{"name":"Radiology - open journal","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75879471","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}

Hence, with the increasing need for radiation dose reductions in CT, the use of artificial intelligence (AI) in image reconstruction has been an area of growing interest. Aim The aim of this review is to examine the use of AI in CT image reconstruction and its effectiveness in enabling further dose reductions through improvements in image quality of low-dose CT images. Method A review of the literature from 2016 to 2020 was conducted using the databases Scopus, Ovid MEDLINE, and PubMed. A subsequent search of several well-known journals was performed to obtain additional information. After careful assessment, articles were excluded if they were not obtainable from the databases or not available in English. Results This review found that deep learning-based algorithms demonstrate promising results in improving the image quality of low-dose images through noise suppression, artefact reduction, and structure preservation in addition to optimising IR methods. Conclusion In conclusion, with the two AI-based CT systems currently in clinical use showing favourable benefits, it is expected that AI algorithms will continue to proliferate and enable significant dose reductions in CT imaging.","PeriodicalId":91603,"journal":{"name":"Radiology - open journal","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80936052","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}
