Low field portable MRI (LF pMRI) is a new imaging tool that holds promise in offering a safe, cost-effective, point-of-care imaging solution in neuroimaging. There are however unique interpretive challenges and operational factors and limitations in its implementation in clinical practice. This paper aims to provide a comprehensive guide on the tips and tricks of interpreting LF pMRI, specifically the Hyperfine Swoop® MRI system, which operates at 0.064T and is currently the only FDA and Health Canada approved LF pMRI system. This paper explores the operational aspects and interpretation challenges of low-field MRI, such as patient positioning, protocol selection, and the appearance of artifacts and common pathologies. Using illustrative examples, we aim to guide current and future operators of LF pMRI to optimize performance, provide accurate diagnoses, and avoid common pitfalls.
