India’s First Indigenously Developed MRI Scanner

Source:  ET

Context: AIIMS New Delhi is set to install India’s first indigenously developed MRI scanner for clinical evaluation.

  • The initiative aims to reduce dependency on imported medical devices and promote ‘Make in India’ innovation.

About India’s first indigenously developed MRI scanner:

  • What it is:
    • The first fully indigenously developed 1.5 Tesla MRI scanner designed for advanced medical imaging and clinical trials.
  • Developed by:
    • Developed by SAMEER (Society for Applied Microwave Electronics Engineering and Research), an autonomous R&D body under Ministry of Electronics and IT (MeitY).
  • To be installed in:
    • Planned installation at AIIMS New Delhi by October 2025 for clinical evaluation and feedback.
  • Project under:
    • Developed under the national mission SCAN-ERA (Swadeshi Chumbakiya Anu-naad Chitran – Ek Rashtriya Abhiyaan), started in December 2014.
  • Key Features:
    • Indigenous technology aimed at reducing treatment costs.
    • 1.5 Tesla MRI system designed to match global clinical standards.
    • Backed by government’s PLI scheme for medical devices.
    • Complements development of other critical devices like CT scanners, LINACs, and heart valves under PLI.

About MRI Scanner Working:

    • MRI uses strong magnetic fields and radiofrequency pulses to align and excite protons in body tissues.
    • As protons realign with the magnetic field, they release energy, which sensors capture to create 3D anatomical images.
  • Used for:
    • Imaging of soft tissues, brain, spinal cord, muscles, ligaments, and tendons.
    • Detecting tumors, aneurysms, neurological disorders, and musculoskeletal injuries.
    • Functional MRI (fMRI) tracks brain activity during cognitive tasks.
  • Risks associated:
    • Magnetic interference: Dangerous for patients with implants like pacemakers or cochlear devices.
    • Noise discomfort: Loud clicking sounds may cause discomfort; ear protection is recommended.
    • Claustrophobia: Patients may face anxiety inside closed MRI tunnels; open MRI systems address this issue.
    • Contrast agents: Risk of nephrogenic systemic fibrosis in dialysis patients from gadolinium-based agents.
