Cobalt-55 positron emission tomography in late-onset epileptic seizures after thrombo-embolic middle cerebral artery infarction

Journal of the Neurological Sciences, 2000
The pathogenesis of late-onset epileptic seizures after thrombo-embolic cerebral infarction is poorly understood. Our previous positron emission tomographic (PET) studies with 15O have demonstrated that post-apoplectic epilepsy is associated with more severe brain ischemia, but we were unable to determine if this was the cause or the consequence of the

Nuclear alinement of cobalt and the decay of cobalt-55

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1961
Cobalt-55 has been alined in a crystal of nickel, zinc fluosilicate which was magnetically cooled to 0.004°K, and the anisotropy of the 0.935 and 1.41 MeV radiations studied as a function of temperature. On the assumption that the spin of 55 Co is 7/2, the spins of the 0, 0.935 and 1.41 MeV levels in 55

Visualization of damaged brain tissue after ischemic stroke with cobalt-55 positron emission tomography.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1994
In animal experiments, the radionuclide 55Co2+ has been shown to accumulate in degenerating cerebral tissue similar to Ca2+.The potential role of 55Co2+ for in vivo brain PET imaging was investigated in four patients after ischemic stroke.PET showed uptake of 55Co2+ in damaged brain tissue irrespective of blood-brain barrier integrity, as affirmed by ...
