Positron Emission Tomography Scan
Market Outlook 2032: Role in Early Disease
Detection and Monitoring
The positron emission tomography scan market is growing steadily as demand rises for precise
diagnostic imaging across oncology, neurology, cardiology, and infectious disease care. PET scanners
(including PET/CT and PET/MRI systems) provide metabolic and anatomical insights, enhancing early disease
detection, treatment planning, and therapy monitoring. Growth drivers include increasing prevalence of
chronic disorders like cancer and neurological conditions, technological advances (such as time-of-flight
detectors, LSO crystals, and AI-enhanced imaging), and greater healthcare investments—especially in
regions like North America and Asia-Pacific. Challenges like high equipment costs, limited radiotracer access,
and skilled staffing shortages remain, but ongoing innovation and policy support are expected to fuel steady
market expansion globally.
According to Fortune Business Insights, the global positron emission tomography (PET) scan market was
valued at USD 18.52 billion in 2024. The market is projected to grow from USD 19.31 billion in 2025 to USD
27.40 billion by 2032, exhibiting a CAGR of 5.1% during the forecast period. In 2024, North America
dominated the PET scan market with a market share of 50.59%.
