Study Notes
Magnetic Resonance Imaging (MRI) Development
- Felix Bloch and Edward Purcell were awarded the Nobel Prize in 1952 for discovering the magnetic resonance phenomenon independently.
- Between 1950 and 1970, NMR was developed and used for chemical and physical molecular analysis.
- In 1971, Raymond Damadian showed that the nuclear magnetic relaxation times of tissues and tumors differed.
- In 1973, the x-ray-based computerized tomography (CT) was introduced by Hounsfield, and Magnetic Resonance Imaging (MRI) was first demonstrated on small test tube samples by Paul Lauterbur.
- Lauterbur used a back projection technique similar to that used in CT scans.
Advances in MRI Technology
- In 1975, Richard Ernst proposed magnetic resonance imaging using phase and frequency encoding, and the Fourier Transform.
- In 1977, Raymond Damadian demonstrated MRI called field-focusing nuclear magnetic resonance, and Peter Mansfield developed the echo-planar imaging (EPI) technique.
- In 1980, Edelstein and coworkers demonstrated imaging of the body using Ernst's technique.
- In 1986, the imaging time was reduced to about five seconds and 10 μm.
- In 1987, echo-planar imaging was used to perform real-time movie imaging of a single cardiac cycle.
Advancements and Recognition
- Charles Dumoulin was perfecting magnetic resonance angiography (MRA) without the use of contrast agents.
- In 1992, functional magnetic resonance imaging (fMRI) was developed, allowing mapping of the function of different areas of the human brain.
- In 2003, Paul C. Lauterbur and Sir Peter Mansfield were awarded the Nobel Prize in Medicine for their discoveries concerning magnetic resonance imaging.
