Abstract
Imaging with nuclear magnetic resonance (NMR) is a sensitive indicator of the location and extent of brain edema [1, 2]. Indeed, preliminary studies indicate that NMR imaging gives better definition of the extent and mass effects of edema than is achievable at present with X-ray computed tomography (CT) [1, 3]. CT gives information only on tissue density (i.e., the coefficient of linear X-ray absorption), whereas proton NMR provides information related to the density of mobile hydrogen and to its relaxation behavior; i.e., the longitudinal (T1) and transverse (T2) relaxation times. The corresponding relaxation rates are given as 1/T1 and 1/T2.
The study described in this paper was supported by grants from the Alberta Heritage Foundation for Medical Research (major equipment) and the Alberta Heritage Savings Trust Fund for Applied Research — Cancer (H-184: H-340). MEC is an Alberta Heritage Foundation for Medical Research Fellow.
