Medical isotopes are essential for diagnostic imaging (particularly SPECT and PET) and an expanding range of therapeutic applications in oncology and other areas. Production relies primarily on nuclear reactors and accelerators, with technetium-99m remaining the most widely used diagnostic isotope.

At the foundation of nuclear medicine supply is the Medical Isotope Production Market, valued at approximately USD 6.7–7.5 billion in 2025–2026 and projected to reach USD 15–18 billion by 2040 at CAGRs in the 6–8% range. Commercial-scale production dominates current volume.

Key producers include Cardinal Health, Curium, NorthStar, NTP Radioisotopes, and others. Rising demand for both diagnostic procedures and targeted radi­opha­rmac­euti­cal therapies is expected to support continued market expansion.
