Low-cost MRI machine can improve access to diagnostics in India

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.
