Proton Spin Tomography in Brain Edema
Proton magnetic resonance studies, and especially spectro-metric techniques possessing great selectivity, allow the detailed analysis of the states of water in brain edema and brain tumors8,2. On the basis of the correlation between the relaxation times T1 and T2 and tissue water content observed for tumor tissue and brain tissue with various types of ederna4,10,1,6,3 it was predicted that an imaging technique could be devised depicting brain lesions on the basis of their increased water content, provided that the relaxation times could be encoded into a signal.
