Use of 7-Tesla Magnetic Resonance Imaging: The Future Perspectives

Neuroimaging using the 7-Tesla (7T) magnetic resonance (MR) system is rapidly gaining popularity after being approved for clinical use in the European Union and the USA. This trend is the same for functional MR imaging (MRI). The primary advantages of 7T over lower magnetic fields are its higher signal-to-noise and contrast-to-noise ratios, which provide high-resolution acquisitions and better contrast, making it easier to detect lesions and structural changes in brain disorders. 7-Tesla (T) scanner is the latest apex in the rapidly changing development of magnetic resonance imaging (MRI), a technique that makes three-dimensional images of internal organs. The 7-Tesla's ultra-strong magnet about 140,000 times as strong as the Earth's magnetic field— yields spectacular images of the human brain at a resolution of about 1/5 of a millimetre. Another advantage is the capability to measure a great number of Neuro Chemical by virtue of the increased spectral resolution.
