3.0-Tesla: OPPORTUNITIES AND CHALLENGES

摘要

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.
