Damadian Conceives of and proposes whole body MR scanner for the first time

Key Discovery makes MR Scanner Possible

1970

1970- Key Discovery Makes MR Scanner Possible
Damadian identifies T1/T2 differences between cancer and normal. He was seeking an MR signal difference in an important disease (cancer) that would prove his idea of an MR body scanner was a goal worth pursuing.
