Cyclotron production of carrier-free cobalt-55, a new positron-emitting label for bleomycin

The International Journal of Applied Radiation and Isotopes, 1979
A method for producing carrier-free 55Co (18.5 h) by proton bombardment of natural iron targets is presented. 55Co is formed primarily by means of the 56Fe (p, 2n)55Co reaction. Thin-target and thick-target yields as well as cross-section calculations are given in the 15-MeV to 40-MeV proton-energy range. Half-life measurements indicate a value of 18.5

Cobalt-55 Positron Emission Tomography of Ipsilateral Thalamic and Crossed Cerebellar Hypometabolism after Supratentorial Ischaemic Stroke

Cerebrovascular Diseases, 1999
Cobalt-55 (⁵⁵Co) is a positron emission tomography (PET) tracer used to demonstrate brain damage, possibly associated to calcium-mediated processes. The degree of ⁵⁵Co accumulation correlates with the severity of ischaemia in stroke patients.

Cobalt-55 positron emission tomography in symptomatic atherosclerotic carotid artery disease: borderzone versus territorial infarcts

Clinical Neurology and Neurosurgery, 2004
Borderzone as well as territorial infarcts can occur in severe atherosclerotic carotid artery disease. It remains controversial whether the borderzone distribution of infarcts is due to hypoperfusion or due to artery-to-artery embolism.The present study investigates whether cobalt-55 (55Co) positron emission tomography (PET) shows a different pattern ...

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

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 ...
