Emerging low-field systems (&lt;1 T) cut equipment and operating costs and consume far less power, making them attractive for low- and middle-income countries (LMICs). We conducted a narrative review of human studies from LMICs that reported clinical, economic or environmental outcomes of low-field MRI, paying special attention to cardiovascular applications and implementation issues in Pakistan. Across included papers, low-field scanners lowered capital expenditure, energy consumption and siting requirements while maintaining diagnostic performance comparable to high-field units in several settings, notably musculoskeletal imaging and intra-operative guidance. Evidence for cardiovascular imaging remains scarce, and key barriers\u2014lower spatial resolution, limited local expertise and infrastructure gaps\u2014persist. Nonetheless, low-field MRI offers Pakistan a feasible, environmentally sustainable option for clinical imaging more broadly; direct evidence for cardiovascular applications, however, remains limited and largely indirect, so routine cardiovascular use will require dedicated validation and further technical refinement before it can be recommended.<\/jats:p>","DOI":"10.1177\/00469580261484300","type":"journal-article","created":{"date-parts":[[2026,10,1]],"date-time":"2026-10-01T11:17:24Z","timestamp":1790853444000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Low-Field
