体内正常脑组织和水肿（瘤周）脑组织中获得的核磁共振 (NMR) 纵向弛豫时间（T1 值）与手术样本重量分析获得的脑水测量值之间存在关系。在 7 名患者的皮质（r = 0.97，P < 0.001）和白质（r = 0.92，P < 0.001）中发现显着相关性。这些发现表明核磁共振可能被证明是监测脑水肿的有用技术。
A relationship has been demonstrated between nuclear magnetic resonance (NMR) longitudinal relaxation times (T1 values) obtained in vivo in both normal and oedematous (peritumoral) brain tissue, and measurements of brain water obtained by gravimetric analysis of operative samples. Significant correlations were found in seven patients in both cortex (r = 0.97, P < 0.001) and white matter (r = 0.92, P < 0.001). These findings suggest that NMR may prove a useful technique for monitoring brain oedema.
