History of Magnetic Resonance Imaging(MRI) technology
The history of Magnetic Resonance Imaging technology starts with the study of magnetism, or in other words , the way that electrons and atoms respond to magnetic fields. In the 1930s, the scientist Dr. Rabi developed a method for measuring the magnetic field . In his work, Dr. Rabi invented a form of MRI called the technology of nuclear magnetic resonance (NMR). This work is considered as the basis of clinical MRI.
In the 1940s, scientists Felix Bloch and Edward Purcell, both worked independently, investigated atomic magnetism and the magnetism of two phases the solids and the liquids. Their investigation then allowed MRI scanners to use the fluid in the body to create magnetic images.
In 1952, the physicists Dr. Purcel and Dr. Bloch won the Nobel Prize in physics.

By the end of 1969, Dr. Raymond Damadian proposed a hypothesis that magnetic fields could distinguish cancer cells from non-cancerous cells, and succeeded to prove this hypothesis in rats.
Based on this research, he designed the first MRI body scanner in 1969.during 1972, Dr. Damadian applied for the the first patent for MRI technology. After his patent was approved in 1974, Damadian built a full featured MRI machine.
The essential role of magnetic resonance imaging (MRI)
nowadays , MRI technology continues to evolve as a great tool in the medical sector especially as the clinical imaging becomes increasingly vital in the prevention and diagnosis of cancer, as well as the diagnosis of other diseases. magnetic resonance imaging technology can help doctors make clear diagnoses by distinguishing between different types of affected tissue in human body especially cancer cells.

World's Most Powerful MRI
Scientists at Atomic Energy Commission (CEA) in France used the machine for the first time to analyze pumpkin in 2021. But after the complete development of the machine , recently health officials gave it the green light to test this powerful MRI on human brain .
The great design is the result of twenty years of research and collaboration between French and German scientists The United States and South Korea are working on a similar MRI device, but have not yet begun analyzing human images.

New hope for patients with Alzheimer's
Researchers hope that the new powerful MRI SCANS will give a clearer image to the different parts of the brain and also can also bring the light on the mechanisms that can be caused by neurodegenerative diseases such as Parkinson's or Alzheimer's, or mental illnesses such as depression or schizophrenia. This could also help to identify identify which A lzheimer patients will respond to the new developed drug.
