Autosegmentation, however, introduces challenges due to uncertainties that arise from factors such as limited training data and models. A nuanced understanding of these uncertainties is essential, as they directly impact clinical decisions and patient outcomes. We explore the sources of uncertainties and how they may be quantified, highlighting the impact on different levels of the segmentation process and discussing the implications of imperfect predictions. Practical applications are proposed, such as uncertainty maps to guide manual adjustments and flagging mechanisms to support quality assurance. We finally address the limitations of these approaches, including computational burdens and risks of information overload. Meaningful uncertainty quantification in autosegmentation holds significant potential to enhance clinical workflows, build trust in artificial intelligence-based tools, and ultimately improve patient care in radiotherapy.</p>","PeriodicalId":517427,"journal":{"name":"BJR artificial intelligence","volume":"2 1","pages":"ubaf013"},"PeriodicalIF":0.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13045711/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147825585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review explores the potential of artificial intelligence (AI) in CT dosimetry. Using machine learning models, trained with extensive data from personalized Monte Carlo dosimetry, AI significantly enhances the dosimetry process by providing accurate, rapid dose assessments. It automates organ segmentation from CT images, a critical and traditionally time-consuming step, enabling precise estimation of organ doses. AI's ability to predict dose distributions with high accuracy facilitates the seamless integration of personalized dosimetry into clinical workflows, promising improved patient safety and optimized radiation dose management. Additionally, AI-driven approaches offer substantial advancements over conventional methodologies, which often face challenges such as prolonged computation times and labour-intensive manual processes. Despite these advancements, challenges hinder the widespread adoption of AI in CT dosimetry.
