Fundamental problems in NMR imaging

The authors have developed an imaging modality called the magic angle rotating frame method. This modality uses a signal-to-noise ratio comparable to that of standard methods. The authors have demonstrated the possibility of using their method to obtain spatial information on a 20-kHz bandwidth system. They have used paramagnetic tracers to emphasize relaxation time contrast and selecting certain pathological tissues for a direct in vivo diagnosis of the nature of the pathology.
