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.
