High Field Diffusion Tensor Imaging in Small Animals and Excised Tissue be used to help understand diffusion processes. Diffusion MR imaging is most widely used for imaging the ischemic brain. Diffusion imaging and diffusion tensor imaging (DTI) have also found clinical application in areas such as tumor characterization throughout the body, imaging of demyelinating di

Hyperpolarized Noble Gases as Contrast Agentswn great potential for applications in lung magnetic resonance imaging (MRI) by greatly enhancing the sensitivity and contrast. These gases obtain a highly polarized state by employing a spin exchange optical pumping technique. In this chapter, the underlying physics of spin exchange optical pumping

MRI Using Intermolecular Multiple-Quantum Coherencesions. In the last few years, these signals have been used for a wide range of applications in imaging and high-resolution spectroscopy. Recent applications include MRI contrast enhancement, suppression of inhomogeneous broadening in NMR experiments, and more recently, in vivo temperature measurement
