Low-Cost MRI Scanner Makes Diagnostics More Accessible
MRI Scans Explained: MRI (magnetic resonance imaging) scans use strong magnetic fields and radio waves to produce detailed images of organs and tissues inside the body.
Current Limitations: High-field MRI machines are expensive, require specialized infrastructure, and limit access in low- and middle-income countries.
New Low-Cost Design: Researchers developed a low-cost MRI scanner using weaker magnets and common hardware, bringing down the cost to around $22,000.
Addressing Challenges:
Lower image resolution is addressed using deep-learning algorithms to improve image quality.
Weaker magnets eliminate the need for a shielded room and liquid helium coolant.
Potential Benefits:
Increased access to MRI scans in remote areas and low-income settings.
Improved emergency care with faster diagnosis and treatment decisions.
Reduced risk of accidents due to metal objects getting pulled into the machine.
Future Considerations:
More testing is needed in different clinical settings.
The scanner may complement, but not replace, high-field MRI machines for detailed diagnoses.
