Article Abstract
We have a large clinical experience (>500 patients) with the ultra-low-field, portable brain MRI (Swoop Portable MR Imaging System, Hyperfine; www.hyperfine.io). This video article gives an overview of the scanner characteristics, scan procedure, and representative clinical images obtained from our experience. The portable MRI system is a useful adjunct to high-field MRI for critically ill patients, avoiding the time and risks associated with moving critically ill patients and their life support teams from the intensive care unit to the conventional scanner. The ultra-low-field environment also allows for decreased susceptibility artifacts and improved safety, allowing patients with active and passive medical devices to have diagnostic MRI, which may not be otherwise available. We demonstrate substantial artifact reduction from extensive dental amalgam as well as safe scanning of a patient with a non-MR-conditional pacemaker. The ability to detect contrast enhancement at ultra-low-field with standard-dose IV gadolinium is also shown.

Malathion, a prevalent organophosphorus pesticide (OP), represents a significant hazard to human health and the environment. In this research, we utilized an alkaline phosphatase (ALP)-sensitive method for the simultaneous detection and partial degradation of malathion. Malathion inhibits ALP activity, reducing the reaction signal it catalyzes, which allows for its detection.

Introduction: Neuroimaging is a prerequisite for treatment of stroke patients, but it is not available all over the globe. Portable ultra-low field (pULF) MRI has the potential to improve access to neuroimaging and thus stroke care worldwide. In a pilot study, we were the first to utilise pULF-MRI in a European tertiary stroke centre and to evaluate its diagnostic value compared to high-field (HF) MRI.

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.

The detection of transient peri-ictal magnetic resonance imaging (MRI) abnormalities has been variable after epileptic seizures. The most common reason for this variability is that abnormalities may disappear if the interval between seizure and scan acquisition is prolonged using conventional high-field systems. Here, we deployed a portable ultra-low-field MRI system in the presurgical evaluation at the bedside of individuals with epilepsy.
