Positron emission tomography in primary brain tumours using cobalt-55

Nuclear Medicine Communications, 1997
Primary brain tumours are usually assessed by computed tomography (CT) and magnetic resonance imaging (MRI), sometimes in conjunction with positron emission tomography (PET). We used cobalt-55 (55Co) as a calcium (Ca) tracer to visualize decaying tumour tissue, based on the fact that Ca-influx is essential in both cell death and leukocyte activation ...

Cobalt-55 positron emission tomography in ischemic stroke

Clinical Neurology and Neurosurgery, 1997
After acute cerebral stroke, the (peri-) infarct tissue is characterized by calcium (Ca)-mediated neuronal damage and inflammatory processes. Monitoring Ca-mediated damage using the isotope cobalt-55 (Co) as a Ca-tracer may enable PET-imaging of this tissue.

Nuclear alinement of cobalt and the decay of cobalt-55

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1961
Abstract 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 55Co is 7/2, the spins of the 0, 0.935 and 1.41 MeV levels in 55Fe are 3/2, 5/2 and 7/2 ...

The significance of cobalt-55 positron emission tomography in ischemic stroke

Journal of Stroke and Cerebrovascular Diseases, 1999
Cobalt-55 ((55)Co) has been shown to be an interesting positron emission tomography (PET) tracer that may reflect calcium (Ca) influx in damaged cerebral tissue. Because Ca load is important in the ischemic cascade, the exact meaning of (55)Co PET in stroke patients has to be shown.

Cobalt-55 positron emission tomography in recurrent ischaemic stroke

Clinical Neurology and Neurosurgery, 1999
The present study investigates if Cobalt-55 (55Co) positron emission tomography (PET) allows us to distinguish and detect recent, recurrent strokes in patients who had already suffered a previous infarct in the same vascular territory. Fourteen patients with recurrent strokes underwent a 55Co PET scan of the brain. Recently infarcted areas, less than 2

Cobalt-55 positron emission tomography in relapsing-progressive multiple sclerosis

Journal of the Neurological Sciences, 1995
Multiple sclerosis (MS) is an immune-mediated disease of the white matter in the brain that can have a progressive course. However, the progression of relapsing-remitting (RR) MS into relapsing-progressive (RP) MS might represent a more fundamental change in disease activity, i.e. decay of vulnerable neurons and oligodendrocytes.

Production of cobalt-55, a short-lived, positron emitting radiolabel for bleomycin

International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1986
The production and radiochemical separation of 55Co from deuteron irradiation of enriched 54Fe target is described. Methods used for the recovery and reuse of the target material (54Fe) are also described. The yield of 55Co at 12 MeV incident deuteron energy is 1.7 mCi per mu Ah at end of bombardment and the contamination with 57Co is 0.016%.

A PSMA Ligand Labeled with Cobalt-55 for PET Imaging of Prostate Cancer

Molecular Imaging and Biology, 2017
Prostate-specific membrane antigen (PSMA) comprises a recognized target for molecular imaging of prostate cancer. As such, radiolabeled PSMA inhibitors are of great value for diagnosis and staging of this disease. Herein, we disclose the preclinical characterization of [55Co]PSMA-617 for positron emission tomography (PET)/x-ray computed tomography (CT)
