“…CVD related deaths in Sub-Saharan Africa (SSA) have increased by >50% in the past three decades. 66 In SSA, CVDs are responsible for approximately 37% of all chronic disease-related deaths 67 with the most common all-cause-related CVD death being ischemic heart disease, stroke, and hypertensive heart disease. 66 , 68 Notably, the World Health Organization (WHO) estimates the prevalence of hypertension as the highest in the African region, with about 46% of adults aged 25 years and older being hypertensive compared to the rest of the world.…”

Cardiovascular disease continues to be a major burden facing healthcare systems worldwide. In the developed world, cardiovascular magnetic resonance (CMR) is a well-established non-invasive imaging modality in the diagnosis of cardiovascular disease. However, there is significant global inequality in availability and access to CMR due to its high cost, technical demands as well as existing disparities in healthcare and technical infrastructures across high-income and low-income countries. Recent renewed interest in low-field CMR has been spurred by the clinical need to provide sustainable imaging technology capable of yielding diagnosticquality images whilst also being tailored to the local populations and healthcare ecosystems. This review aims to evaluate the technical, practical and cost considerations of low field CMR whilst also exploring the key barriers to implementing sustainable MRI in both the developing and developed world.

“…While cardiovascular disease has decreased globally over recent decades, 10 its incidence is steadily increasing in SSA. 11,12 By enabling accurate assessment of cardiac morphology, function, flow, perfusion, acute tissue injury, and fibrosis, MRI can help determine disease etiology and risk, thus facilitating effective management of heart failure and other cardiomyopathies, 13 even at low magnetic field strengths. 14 MRI is the recommended standard of care in the diagnosis and treatment of neurological diseases, including, but not limited to, seizures, 15 strokes, 16,17 and dementia.…”

Magnetic resonance imaging (MRI) technology has profoundly transformed current healthcare systems globally, owing to advances in hardware and software research innovations. Despite these advances, MRI remains largely inaccessible to clinicians, patients, and researchers in low‐resource areas, such as Africa. The rapidly growing burden of noncommunicable diseases in Africa underscores the importance of improving access to MRI equipment as well as training and research opportunities on the continent. The Consortium for Advancement of MRI Education and Research in Africa (CAMERA) is a network of African biomedical imaging experts and global partners, implementing novel strategies to advance MRI access and research in Africa. Upon its inception in 2019, CAMERA sets out to identify challenges to MRI usage and provide a framework for addressing MRI needs in the region. To this end, CAMERA conducted a needs assessment survey (NAS) and a series of symposia at international MRI society meetings over a 2‐year period. The 68‐question NAS was distributed to MRI users in Africa and was completed by 157 clinicians and scientists from across Sub‐Saharan Africa (SSA). On average, the number of MRI scanners per million people remained at less than one, of which 39% were obsolete low‐field systems but still in use to meet daily clinical needs. The feasibility of coupling stable energy supplies from various sources has contributed to the growing number of higher‐field (1.5 T) MRI scanners in the region. However, these systems are underutilized, with only 8% of facilities reporting clinical scans of 15 or more patients per day, per scanner. The most frequently reported MRI scans were neurological and musculoskeletal. The CAMERA NAS combined with the World Health Organization and International Atomic Energy Agency data provides the most up‐to‐date data on MRI density in Africa and offers a unique insight into Africa's MRI needs. Reported gaps in training, maintenance, and research capacity indicate ongoing challenges in providing sustainable high‐value MRI access in SSA. Findings from the NAS and focused discussions at international MRI society meetings provided the basis for the framework presented here for advancing MRI capacity in SSA. While these findings pertain to SSA, the framework provides a model for advancing imaging needs in other low‐resource settings.
