Abstract

Purpose The purpose of the present study was to deter- brain temperature difference (affected hemisphere − contralateral mine whether apparent brain temperature imaging using hemisphere: ΔBT) was correlated with cerebral blood volume multi-voxel proton magnetic resonance (MR) spectrosco- (CBV) (r = 0.570) and oxygen extraction fraction (OEF) ratios py correlates with cerebral blood flow (CBF) and metab- (affected hemisphere/contralateral hemisphere) (r =0.641). We olism imaging in the deep white matter of patients with excluded voxels that contained ischemic lesions or cerebrospinal unilateral chronic major cerebral artery steno-occlusive fluid and calculated the mean values of voxel pairs in each pa- disease. tient. The mean ΔBT was correlated with the mean CBF Methods Apparent brain temperature and CBF and metab- (r = − 0.376), mean CBV (r = 0.702), and mean OEF ratio olism imaging were measured using proton MR spectros- (r = 0.774). copy and O-positron emission tomography (PET), re- Conclusions Apparent brain temperature imaging using spectively, in 35 patients.
