Aspects of Clinical Imaging at 7 T

  • Chapter
Ultra High Field Magnetic Resonance Imaging

Part of the book series: Biological Magnetic Resonance ((BIMR,volume 26))

Abstract

The intrinsic improvements in signal-to-noise ratio, spectral dispersion, and susceptibility contrast with increasing static magnetic field strength, B 0, has spurred the development of MR technology from its very first application to clinical imaging. With maturing magnet, RF, and gradient technology, the clinical community has seen the static magnetic field of clinical systems increase from 0.2 to 1.5 to 3.0 T. Today, the “high field” label for human MR research describes initial experiences with 7, 8, and 9.4T systems. While currently primarily research instruments, this technology is bound to cross the boundary into the clinical diagnostic arena as key technical issues are solved and the methodology proves itself for addressing clinical issues. In this chapter we discuss the particular advantages and disadvantages of ultra high field systems for clinical imaging as well as some of the immediate technological challenges that must be solved to derive the full benefit of the extraordinary sensitivity of these systems, which has been glimpsed from their research use.
