Conventional assessment is often hindered by its reliance on postoperative findings, sampling errors, and subjective interobserver variability. This review evaluates how artificial intelligence (AI), digital pathology, and MRI radiomics provide earlier, quantitative estimations of LVI-related risk. The strongest direct evidence currently comes from MRI-based studies, where validation performance often reaches area under the receiver operating characteristic curve (AUC) values of 0.84\u20130.90. By contrast, digital pathology is especially mature for LVI-adjacent tasks such as lymph node metastasis detection and slide-based relapse-risk modelling, which together provide an important translational foundation for future LVI-specific tools. This review also addresses issues that remain underdeveloped in the literature, including the distinction between lymphatic and vascular invasion, AI-specific risk-of-bias and reporting frameworks, the emerging regulatory landscape for adjacent breast AI tools, and the gap between resection-based development datasets and biopsy-level preoperative use. Although most modern computational models are developed using extensive surgical resection specimens, their true clinical utility hinges on successful validation and performance within the highly restricted, fragmented tissue context of preoperative core needle biopsies. Overall, the field appears most promising when LVI prediction is framed not as an isolated binary task, but as one component of a broader metastatic-risk workflow that supports calibrated, multidisciplinary breast cancer decision-making.<\/jats:p>","DOI":"10.3390\/jcm15145381","type":"journal-article","created":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T11:55:32Z","timestamp":1783598132000},"page":"5381","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Artificial Intelligence and Digital Pathology for Preoperative Lymphovascular Invasion and Metastatic Risk Prediction in Breast Cancer: Bridging the Biopsy\u2013Resection Gap"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-9284-4262","authenticated-orcid":false,"given":"Bandar S.","family":"Alshreef","sequence":"first","affiliation":[{"name":"Department of Clinical Laboratory Sciences, College of Applied Medical Sciences, Shaqra University, Shaqra 11961, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2507-2292","authenticated-orcid":false,"given":"Yousif A.","family":"Kariri","sequence":"additional","affiliation":[{"name":"Department of Clinical Laboratory Sciences, College of Applied Medical Sciences, Shaqra University, Shaqra 11961, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,9]]},"reference":[{"key":"ref_1","first-page":"209","article-title":"Global Cancer Statistics 2020: GLOBOCAN Estimates of Incidence and Mortality Worldwide for 36 Cancers in 185 Countries","volume":"71","author":"Sung","year":"2021","journal-title":"CA Cancer J.
