title: 3. 0-Tesla: opportunities and challenges.
abstract: With the development of magnetic resonance (MR) technology, the concern is focused on molecular and physiological imaging besides structural information. Ultra high field MR scanner shows great superiority. 3. 0-T MR scanners provide almost two-fold signal-to-noise ratio (SNR) compared with a standard 1. 5-T MR scanner. The higher baseline SNR can be converted into a variety of alternative benefits. There are still some other changes brought about by 3. 0-T, such as higher sensitivity to motion, susceptibility effect, more difference in resonant frequency among different metabolites, and so on. These features may be a double-edged sword in structural and functional imaging. But with the ceaseless progress of the technology and gains in experience, 3. 0-T systems will provide more information and show more advantages.
