Isotopes

A gamma-emitting SPECT workhorse with a 2.8-day half-life, used for white blood cell labeling, peptide receptor imaging (Octreoscan), and antibody pharmacokinetics.

A long-lived positron emitter (β⁺, 3.3 days) matched to the slow kinetics of monoclonal antibodies — the standard isotope for immuno-PET imaging.

A novel positron emitter (β⁺) with a 3.1-hour half-life, produced on standard medical cyclotrons via ⁴⁵Sc(p,n)⁴⁵Ti. An emerging PET tracer well suited to antibody and peptide imaging.

A positron-emitting (β⁺) theranostic isotope and calcium analogue. Its 17.5-hour half-life supports PET perfusion imaging and the study of longer biological processes.

A long-lived gamma emitter (271.8 days) widely used as a calibration and reference source for gamma cameras, flood-field uniformity, and Mössbauer spectroscopy.

A versatile theranostic isotope with a unique triple decay mode (β⁺/β⁻/EC). Its 12.7-hour half-life supports extended imaging windows and regional distribution.

The beta-emitting therapeutic partner to Copper-64, enabling a true image-and-treat theranostic pair with identical chemistry across diagnosis and therapy.

A novel positron emitter (β⁺) and Gallium-68 alternative whose 4-hour half-life extends imaging windows and enables centralized distribution of PET tracers.

The positron-emitting (β⁺) imaging partner to therapeutic Yttrium-90, enabling accurate pre-treatment PET dosimetry within theranostic workflows.

A pure beta emitter (β⁻) and one of the most established therapeutic isotopes — the active radionuclide in liver radioembolization microspheres and radioimmunotherapy.

The cyclotron-produced parent of the Rubidium-82 generator — the backbone of cardiac PET perfusion imaging. Produced at high energy via ⁸⁵Rb(p,4n)⁸²Sr.

A high-activity beta/gamma emitter and the global standard for industrial radiography (NDT) and high-dose-rate brachytherapy. Reactor-produced via neutron capture on Iridium-191.

A reactor-produced beta/gamma emitter used as an industrial radiotracer for flow studies, sediment transport analysis, and neutron flux monitoring.

A reactor-produced beta/gamma emitter used in antimony–beryllium (Sb–Be) photoneutron sources, industrial radiography, and pipeline tracing.
