PURPOSE OF REVIEW: This review aims to describe recent advances in low-field (0.064 T) magnetic resonance imaging (LF-MRI) of cerebrovascular disease, including ischemic and hemorrhagic stroke and white matter hyperintensities.
RECENT FINDINGS: Since 2023, several studies have highlighted the rapidly changing landscape of portable, low-field MRI (LF-MRI) and its applications in stroke and cerebrovascular disease. The advantages of using LF-MRI in these settings are multifold: cheaper and dynamic imaging of this patient population confers closer observation during the acute and chronic stages of cerebrovascular disease. Initial deployments of the device span a variety of acute and emergency settings, including imaging around thrombolytic administration, endovascular reperfusion, intracerebral hemorrhage management, and cardiovascular intensive care. LF-MRI also has an important role in cerebrovascular disease monitoring and prevention, namely white matter hyperintensity (WMH) progression and vascular and Alzheimer's dementia. Early studies suggest reliable sensitivity and specificity for these pathologies. With further improvements to LF-MRI hardware, software and postprocessing on the horizon, we anticipate the device's ability to provide inexpensive and flexible neuroimaging to a wide array of healthcare settings that treat, prevent, and manage cerebrovascular disease.
SUMMARY: Recent studies indicate that LF-MRI promotes rapid, cost-effective, and clinically useful neuroimaging at various clinical timepoints throughout stroke and cerebrovascular disease progression and management.
