History of the MRI

.

TIMELINE OF THE MRI

• 1946 Felix Bloch and Edward Purcell came up with the idea to use magnets to take pictures of a living being.
  
  
• 1950-1970 Nuclear Magnetic Resonance was used to analyze molecules.
  
  
• 1967 Images of the inside of a body were taken.
  
  
• 1970s For the first brain MRI the subject had to sit still for eight hours and the images took 72 hours to develop.
  
  
• 1971 Raymond Damadian proved that magnetic resonance could be used to help detect diseases by the different nuclear magnetic relaxation times between tissues and tumors.
  
  
• 1972 The second MRI image was taken. It was two dimensional which showed the length and width.
  
  
• 1973 Paul Lauterbur demonstrated magnetic resonance imaging on test tubes.
  
  
• 1977 Dr. Raymond Damadian completed the first whole body MRI scanner which he called "Indomitable."
  
  
• July 3,1977 Dr. Raymond Damadien performed the first whole body scan using Indomitable. It lasted four hours and 45 minutes to complete.
  
  
• 1978 The MRI scanner was used to analyze molecules.
  
  
• 1986 The time to recieve an image decreased to five seconds.
  
  
• 1993 The functional MRI was developed. The images showed the different regions of the brain.
