MRI Full Form

What is the full form of MRI?

The full form of MRI is Magnetic Resonance Imaging. MRI is also known as NMRI (Nuclear Magnetic Resonance Imaging) or MRT (Magnetic Resonance Tomography). MRI is a diagnostic imaging technique used in radiology to display more information about the internal body structures, clearer than X-Ray. It can be used to create representations of the anatomy and physiological functions of the body in both illness and health.


How Does MRI Work

In an MRI machine, the protons of hydrogen in the body synchronize along the magnetic field when connected to the magnet to face the same orientation. Since the human body is all water, all tissue types contain protons of hydrogen which react to the magnetic field. A radio wave transmitted through the body, turning the protons away from the magnetic field at either 900 or 1800.

If this radio wave is switched off, the protons slowly reconfigure to the magnetic field of the MRI and energy is released. Dependent on the quantity of energy generated and the time required to reorient the protons, the MRI will distinguish among tissue types to produce a detailed picture.

Applications Of MRI

  1. MRI used in medical applications. MRI accurately detects health problems and illnesses from the human body.
  2. MRI can be used to treat brain tumours, heart attacks and strokes, head or neck injuries, heart and stroke disorders, spinal disorders, brain and spinal cord defects, joints and bones, liver and other stomach problems, women’s uterine irregularities, etc.

Comparison between MRI scan and CT scan

CT scan Stands for Computed Tomography Scan. MRI is a better option than CT scanning as it creates more preferable images of the internal parts of the body and does not reveal patient or technician to potentially dangerous radiation. In contrast, CT Scan does have this threat.
