    A study of epileptogenic foci with 31P-chemical shift imaging

    The subjects of this study were 36 epilepsy patients aged 8–62 years, who were examined 45 times; 25 had partial and 11, generalised seizures.31-chemical shift imaging (CSI) was acquired with three-dimensional Fo...

    31P-chemical shift imaging of human cerebral infarction

    Twenty patients with cerebral infarcts were investigated with phosphorus chemical shift imaging (31P-CSI) using a 2.0 T MRI and spectroscopy system to monitor the energy metabolism in the infarcted brain. All pat...
