The burden of neurological disorders in low- and middle-income countries (LMICs) may be underestimated due to the limited number diagnostic imaging devices trained specialists operate interpret scans. Recent advancements low-field (<100 milliteslas) magnetic resonance (LFMRI) hold significant promise for improving access pediatric neuroimaging technology's lower costs, portability, reduced infrastructure training requirements. Explore user needs experiences on use a portable LFMRI LMICs. We conducted qualitative interviews with end users systems across 11 sites Bangladesh, Ethiopia, Ghana, Malawi, Pakistan, South Africa, Uganda, Zambia. A semi-structured questionnaire open-ended questions usability feasibility was used encourage participants share their opinions ease use, satisfaction, integration into local health systems. Among 46 participants, key challenges were reported infant positioning, power stability, internet connectivity. Suggestions included developing reference materials content format tailored contexts, conducting refresher trainings, providing education that includes technical maintenance support crucial appropriate utilization implementation sustainability. This study underscores importance incorporating human-centered design principles feedback identifying resolving issues, sharing insights successful within existing care infrastructures LMICs, optimizing populations.

ABSTRACT Introduction Low‐field MRI applications in clinical neuroimaging are becoming very common despite potential limitations that may hinder the ability to meet current expectations relative advanced high‐field strength scanners. The present review offers an in‐depth evaluation of low‐field neuroimaging. Methods This study employed a systematic methodology collect data from primary studies various designs via relevant federated electronic databases EBSCOhost (including Web Science and SCOPUS). included articles were subjected extraction, quality assessment, textual narrative synthesis. Results following themes surrounding developed through qualitative synthesis: (1) field strength, diagnostic accuracy, image applications, including MRI‐guided intraoperative procedures therapeutic planning; (2) advances benefits neuroimaging; (3) geographical spread scanners Conclusions results demonstrate several commercially available identified offer considerable relevance versatility for diverse applications. Despite issues related sensitivity due increased noise, low contrast‐to‐noise ratio, blurring, these factors render them less desirable. Nonetheless, findings this indicate use along with future improvements field, viable cost‐efficient choice conducting imaging procedures. Thus, urgent considerations enhance global accessibility availability services utilizing encouraged.

Abstract Purpose To develop and evaluate a highly efficient free‐breathing contrast‐agent‐free three‐dimensional (3D) whole‐heart Cardiac Magnetic Resonance Angiography (CMRA) sequence at 0.55T. Methods Free‐breathing CMRA has been previously proposed 1.5 3T. Direct application of this to 0.55T is not possible due changes in the magnetic properties tissues. enable 0.55T, pulse design acquisition parameters framework are optimized via Bloch simulations. Image navigators (iNAVs) used nonrigid respiratory motion‐correction 100% scan efficiency. Patch‐based low‐rank denoising employed accelerate account for reduced signal‐to‐noise ratio The approach was evaluated on 11 healthy subjects. quality assessed by clinical expert (1: poor 5: excellent) all intrapericardiac structures. Quantitative evaluation performed assessing vessel sharpness proximal right coronary artery (RCA). Results Optimization resulted an imaging flip angle , fat saturation six k‐space lines iNAV encoding. relevant cardiac structures main arteries were visible subjects, with excellent image (mean ) minimal artifacts ), RCA () comparable previous studies 1.5T. Conclusion enables 3D 6‐min (), providing quality, artifacts, 1.5T studies. Future work will include patients cardiovascular disease.
