It includes only the commonly used and basic terminology imperative for physicians to know. AI is not just a computerized approach but an interface between humans and machines. Apart from reducing workload and improved diagnostic accuracy, radiologists get more time for patient care or clinical work by using various machine learning techniques that augment their productivity. Inadequate data input with suboptimal pattern recognition, data extraction challenges, legal implications, and exorbitant costs are a few pitfalls that AI algorithms still face while analyzing and giving appropriate outcomes. Various machine learning approaches are used to construct prediction models for clinical decision support and ameliorating patient management. Since AI is still in its fledgling state, with many limitations for clinical implementation, clinical support and feedback are needed to avoid algorithmic errors. Hence, both machine learning and human insight complement each other in revolutionizing breast imaging.","PeriodicalId":39053,"journal":{"name":"Reports in Medical Imaging","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45370859","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":"Distinguishing Radiation Pneumonitis from Local Tumour Recurrence Following SBRT for Lung Cancer","authors":"B. Frerker, G. Hildebrandt","doi":"10.2147/rmi.s176901","DOIUrl":"https://doi.org/10.2147/rmi.s176901","url":null,"abstract":": Radiation pneumonitis is one of the most common toxicities following SBRT for lung cancer. Although local control rates are good, a recurrent tumour is dif fi cult to distinguish from radiation pneumonitis due to similar size and morphology. Therefore, early detection of a recurrent tumour is challenging, and moreover, it is crucial for affected patients, as early detection enables curative salvage therapy. Promising data exists to solve these challenges for late recurrences, for example, the analysis of high-risk CT features allows prediction of recurrence after 12 months. But particularly in cases of early recurrences and radiation pneumonitis, comprehensive data are lacking. Therefore, the aim of this study was to review the existing literature with special regard to radiological response assessment after stereotactic body radiotherapy and risk factors for predicting radiation pneumonitis or local recurrence. (PET) is encouraging. Huang et al developed a follow-up algorithm for response-assessment after SBRT, in which a PET is recommended in some cases, and Dong et al demonstrated that patients with high metabolic activity (described as SUVmax) before treatment had a worse overall survival. Nevertheless, the interpretation of a PET-scan should be done carefully as there is no optimal SUVmax threshold for predicting local recurrence or radiation pneumonitis. Another approach is to analyse of dosimetric parameters before performing SBRT, and indeed, some parameters seem to be associated with radiation pneumonitis, but again no speci fi c dose constraints are found yet. We found promising data in the literature, but the results are controversial, and a conclusion could not be drawn.","PeriodicalId":39053,"journal":{"name":"Reports in Medical Imaging","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/rmi.s176901","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46508214","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}

However, recent advances in diffusion MRI have provided further information on brain microstructures using multi-shell protocols of diffusion MRI. Neurite orientation dispersion and density imaging (NODDI) is one such emerging advanced diffusion MRI method that enables investigation of the neurite density and neurite orientation dispersion of brain microstructures. NODDI was developed as a practical and clinically feasible diffusion MRI technique to evaluate the microstructural complexity of dendrites and axons. This review shed light on recent studies on the use of NODDI in human brain. Indeed, a growing number of studies are using NODDI to examine neurological and psychiatric disorders, with most reporting its clinical utility. The time has thus come, for us to seriously consider the clinical use of NODDI.","PeriodicalId":39053,"journal":{"name":"Reports in Medical Imaging","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/RMI.S194083","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42753362","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}

Materials and methods: In order to evaluate a semiautomated segmentation tool, a cone beam computed tomography (CBCT) was selected with 20 intact teeth (10 maxillary and 10 mandibular teeth), CBCT images were imported into the ImageJ software, and the root volumes were measured using two methods (the semiautomated segmentation and the manual segmenta-tion). Both segmentations are carried out by two experts; the manual segmentation served as a reference method and considered as the “gold standard”. The data were analyzed using the Bland–Altman analysis to compare the agreement between methods, and the intraclass correlation coefficient (ICC) was used to assess the interobserver reliability. Results: The Bland–Altman analysis revealed the agreement between measurements on semiautomated segmentation and manual segmentation, with a mean bias of –2.09 mm 3 and the 95% limits of agreement of –11.38 to 7.21 mm 3 . The ICC was 0.999 for semiautomated segmentation method and 0.999 for manual segmentation method. Conclusion: The use of stereology employing the ImageJ software and CBCT images provide an accurate and reliable semiautomated segmentation, leading to an approach of volume quantitative analysis to evaluate and follow-up the root’s volume when orthodontic treatment occurred. Further clinical studies are necessary to explore this method.","PeriodicalId":39053,"journal":{"name":"Reports in Medical Imaging","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/RMI.S153169","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41720093","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}
