Advocacy in Theranostics: Expanding Access and Awareness Across Disciplines.

Theranostics, the combination of diagnostic and therapeutic nuclear medicine, has revolutionized the field by offering patient-specific, targeted treatment options. Although the concept dates back to the early use of radioiodine to treat thyroid disorders, modern theranostics encompasses a wide range of diseases and options and is becoming an integral component of precision medicine. Despite rapid advancement, significant barriers, such as geographic disparities, workforce shortages, regulatory burden, inadequate infrastructure, high costs, and low awareness, among providers and patients limit equitable patient access to theranostic services. Overcoming these barriers will require coordinated action among health care institutions, policymakers, educators, and professional societies to harmonize standards, support workforce expansion, and develop flexible, scalable models of care and training. By uniting stakeholder efforts, embracing innovation, and prioritizing equity, the field can fulfill the promise of theranostics and ensure that these therapies reach all patients.
