🔬 Sc-44: A New Balance in PET Imaging
2026-04-20
In PET imaging, different radionuclides come with different trade-offs.
Short-lived isotopes such as ⁶⁸Ga offer convenience,
while ¹⁸F enables large-scale clinical use.
👉 But what if there is a balance in between?
Scandium-44 (Sc-44) is emerging as a promising option.
With a half-life of around 4 hours, it offers:
• More flexibility than short-lived isotopes
• Longer imaging windows for better tracer distribution
• Potential for improved imaging consistency
👉 A balance between practicality and performance.
💡 Beyond imaging, Sc-44 is part of a theranostic pair with Sc-47, opening new possibilities for connecting diagnosis and therapy.
From a production perspective, Sc-44 also reflects a broader trend:
👉 moving toward cyclotron-based radionuclide production to support more flexible and scalable workflows.
🚀 We’re pleased to share that LBT will be presenting an abstract about automated production of 44Sc using a natural CaO target at SNMMI 2026.
More details coming soon.
