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.
磁共振成像(MRI)技术在硬件和软件研究创新方面的进步,彻底改变了当前的全球医疗保健系统。尽管取得了这些进展,但在资源匮乏地区,如非洲,MRI 仍然在很大程度上无法为临床医生、患者和研究人员所获得。非洲不断增长的非传染性疾病负担突显了改善 MRI 设备获取以及在非洲培训和研究机会的重要性。推进非洲磁共振成像教育和研究联盟(CAMERA)是一个由非洲生物医学成像专家和全球合作伙伴组成的网络,正在实施新策略以促进非洲的 MRI 访问和研究。CAMERA 成立于 2019 年,旨在确定 MRI 使用的挑战,并为该地区的 MRI 需求提供一个框架。为此,CAMERA 在两年的时间里,在国际 MRI 学会会议上进行了一项需求评估调查(NAS)和一系列研讨会。该 68 个问题的 NAS 分发给非洲的 MRI 用户,并由来自撒哈拉以南非洲(SSA)的 157 名临床医生和科学家完成。平均而言,每百万人拥有的 MRI 扫描仪数量仍不到一台,其中 39%是过时的低场系统,但仍在使用以满足日常临床需求。来自各种来源的稳定能源供应的可行性促进了该地区越来越多的高场(1.5 T)MRI 扫描仪的使用。然而,这些系统的利用率很低,只有 8%的设施报告每个扫描仪每天进行 15 次或更多的临床扫描。最常报告的 MRI 扫描是神经和肌肉骨骼。CAMERA NAS 结合世界卫生组织和国际原子能机构的数据,提供了非洲 MRI 密度的最新数据,并为非洲的 MRI 需求提供了独特的见解。报告的培训、维护和研究能力差距表明,在撒哈拉以南非洲地区提供可持续的高价值 MRI 访问仍然存在挑战。NAS 的调查结果和国际 MRI 学会会议上的重点讨论为这里提出的推进撒哈拉以南非洲地区 MRI 能力的框架提供了基础。虽然这些发现适用于撒哈拉以南非洲地区,但该框架为在其他资源匮乏环境中推进成像需求提供了一个模型。
