A scoping review examines machine learning in medical imaging across 2019–2021, mapping the field’s potential, limitations, and future directions. Reported strengths emphasize analytic power, efficiency, improved decision making, and equity, while challenges focus on structural barriers, imaging heterogeneity, limited interoperable datasets, validity and performance limits including bias, and missing clinical integration. Ethical and regulatory implications remain blurred, and explainability and trustworthiness receive limited technical and regulatory detail. Future work is expected to move toward multi-source, more open, explainable models combining imaging with other data streams.","Zurich Open Repository and Archive  \nUniversity of Zurich  \nUniversity Library Strickhofstrasse 39  \nCH-8057 Zurich [www.zora.uzh.ch](www.zora.uzh.ch)  \nYear: 2023  \nBeyond high hopes: A scoping review of the 2019-2021 scientific discourse on  \nmachine learning in medical imaging  \nNittas, Vasileios ; Daniore, Paola ; Landers, Constantin ; Gille, Felix ; Amann, Julia ; Hubbs, Shannon ; Puhan,  \nMilo Alan ; Vayena, Effy ; Blasimme, Alessandro  \nDOI: [https://doi.org/10.1371/journal.pdig.0000189](https://doi.org/10.1371/journal.pdig.0000189)  \nPosted at the Zurich Open Repository and Archive, University of Zurich ZORA URL: [https://doi.org/10.5167/uzh-254056](https://doi.org/10.5167/uzh-254056)  \nJournal Article Published Version  \nThe following work is licensed under a Creative Commons: Attribution 4.0 International (CC BY 4.0) License.  \nOriginally published at:  \nNittas, Vasileios; Daniore, Paola; Landers, Constantin; Gille, Felix; Amann, Julia; Hubbs, Shannon; Puhan, Milo Alan; Vayena, Effy; Blasimme, Alessandro (2023) .
