TI - YOLO in Medical Imaging: Evolution, Clinical Translation, and Future Directions T2 - Computers, Materials \& Continua PY - VL - IS - SN - 1546-2226 AB - Over the past decade, rapid advances in artificial intelligence have substantially expanded applications in medical image analysis, computer-aided diagnosis, and clinical decision support. Among object detection architectures, the YOLO (You Only Look Once) family has emerged as one of the most widely adopted approaches due to its real-time inference capability. However, transferring YOLO from general computer vision to clinical settings still faces major challenges, including small lesion detection and the gap between algorithmic performance and real-world clinical utility. This topical review provides a structured narrative synthesis of YOLO applications in medical imaging from 2016 to 2026. Unlike previous surveys, this work proposes a unified analytical framework and a four-dimensional taxonomy that categorizes studies according to task type, imaging modality, clinical context, and data regime. Based on this framework, the review analyses the architectural evolution of YOLO. To support quantitative analysis, the paper compiles a meta-benchmark table across standard datasets, together with a quality assessment table based on CLAIM 2024 and TRIPOD+AI guidelines. Another contribution is the analysis of the 2010–2015 foundations and the co-evolution of YOLO and modern medicine during 2016–2026, clarifying how medical challenges have shaped algorithmic design and vice versa. The paper also devotes separate sections to three issues often overlooked in previous reviews: (i) dataset and model bias analysis, (ii) the reproducibility crisis in medical AI, and (iii) failure analysis (“Failure modes and limitations of YOLO in medical imaging”). Finally, a four-layer conceptual framework, termed the “Clinical-Aware YOLO Framework,” is proposed to bridge the gap between algorithm development and clinical deployment. This framework remains conceptual and requires prospective validation. The review concludes that the next generation of medical YOLO systems must shift from benchmark-oriented optimization toward clinical awareness, in which algorithmic fairness, reproducibility, and prospective validation are treated as core design requirements.
