Fig. 1: Prototype of a low-cost low-power and shielding-free brain ultra-low-field (ULF) magnetic resonance imaging (MRI) scanner with homogenous 0.055 Tesla magnetic field and small 5 Gauss fringe field. aWith ~2 m2footprint and no radiofrequency/magnetic shielding cages, the scanner can ...
The study involved 13 individuals with autism spectrum disorder and 13 without the disorder. They had a mean age of 22.5 years-old. Each participant completed three MRI brain-imaging sessions after taking either a placebo, the beta-blocker propranolol or the beta-blocker nadolol—which is simil...

If your dog has been recommended for an MRI, you’re likely concerned about the cost. While MRI scans are incredibly useful for diagnosing conditions like brain tumors, spinal issues, or joint problems, they can be expensive—often ranging from $1,000 to $4,000. Fortunately, there arefree...
Radiological examination of the brain is a critical determinant of stroke care pathways. Accessible neuroimaging is essential to detect the presence of intracerebral hemorrhage (ICH). Conventional magnetic resonance imaging (MRI) operates at high magnetic field strength (1.5–3 T), which requires an...

To generate these strong and homogeneous fields, superconducting magnets are required, which accounts for the cost, size and infrastructure demands of high-field MRI scanners. Therefore, access to MRI technology is limited for people residing in low- and middle-income countries1. To increase the ...
