The Breakthrough of Magnetic Resonance Imaging: Revolutionizing Medical Diagnosis

The video discusses the technological breakthroughs of the 1970s, focusing on the development of MRI technology. Pioneered by Professor Sir Peter Mansfield in the UK and Doctor Paul Lataba in the US, MRI allowed non-invasive internal body imaging. The first human MRI scan was conducted in 1977. Since then, the number of MRI scanners has grown significantly. MRI works by using magnetic fields to influence hydrogen atoms, with changes detected by radio frequencies. Current challenges include reducing the noise levels in MRI chambers.
