Global PET Market Expected to Reach $2.81 Billion by 2035, PET-CT Remains Dominant

A market research report shows that the global Positron Emission Tomography (PET) market size is expected to increase from $1.86 billion in 2025 to $2.81 billion by 2035, with a compound annual growth rate (CAGR) of 4.26% from 2026 to 2035. Increased demand for cancer diagnosis, expanded application of hybrid imaging technologies such as PET-CT and PET-MRI, and continued development of molecular imaging technologies are considered major factors driving market growth.

The report points out that PET scans are being increasingly used in scenarios such as cancer detection and treatment evaluation, cardiac disease assessment, and diagnosis of neurological and psychiatric disorders. Meanwhile, population aging, rising healthcare expenditures, and growing demand for early screening are also driving healthcare institutions to expand PET imaging applications. Technological advances such as digital PET scanners, novel radiotracers, AI-assisted image analysis, and total-body PET scanning are further expanding the clinical and research applications of PET.

By product segment, PET-CT systems remain the market mainstay, with an estimated market share of approximately 82% in 2025. Fixed PET scanners are expected to account for approximately 93.10% of the market share, primarily due to their widespread deployment in hospitals and diagnostic facilities. By application area, oncology is expected to account for over 55% in 2025, with PET continuing to play a prominent role in cancer diagnosis, staging, treatment planning, and therapeutic response monitoring. Neurology is considered a faster-growing application segment, covering the diagnosis and treatment of conditions such as Alzheimer's disease, Parkinson's disease, epilepsy, and brain function localization.

By regional market, North America is expected to hold approximately 41.50% of the global market in 2025, maintaining a leading position. The U.S. PET market is expected to grow from approximately $680 million in 2025 to $910 million by 2035, with a CAGR of 2.98%. The European market is expected to increase from $520 million in 2025 to $760 million by 2035, with a CAGR of 4.10%. The Asia-Pacific region is considered the fastest-growing regional market, driven primarily by increased healthcare spending, a high cancer burden, and the adoption of advanced imaging equipment in countries such as China, India, Japan, South Korea, and Australia. The report estimates that China accounts for approximately 29.00% of the Asia-Pacific market.

The report also mentions that in 2024, GE HealthCare announced an investment of $960 million in India to expand manufacturing and R&D capabilities for PET-CT diagnostic imaging systems and related medical equipment. In 2025, Canon Medical Systems launched the next-generation Alphenix 4D CT, integrated with the Aquilion ONE / INSIGHT Edition to support advanced hybrid imaging applications. Overall, PET market growth will continue to revolve around oncology diagnosis and treatment, hybrid imaging system upgrades, and the expansion of nuclear medicine molecular imaging technologies.
