Positron-Emission Tomography (PET) Market Size & Industry Outlook
The global positron-emission tomography (PET) market size reached US$ 2.69 Billion in 2024 from US$ 2.56 Billion in 2023 and is expected to reach US$ 4.29 Billion by 2033, growing at a CAGR of 5.4% during the forecast period 2025-2033. The global Positron Emission Tomography (PET) market has been experiencing robust growth, driven by technological advancements, rising prevalence of chronic diseases, and expanding clinical applications. PET imaging has gained widespread adoption across both developed and emerging markets due to its ability to provide detailed functional and metabolic information that complements anatomical imaging.
Based on product type, hybrid PET systems dominate the market because they combine functional imaging from PET with anatomical imaging from CT or MRI, providing more precise and comprehensive diagnostic information than standalone PET scanners. This dual capability is especially critical in oncology, where accurate tumor localization and staging directly influence treatment decisions. Additionally, novel product launches further boosting the segment growth.
For instance, in December 2024, United Imaging introduced two new products at RSNA 2024: uMR Ultra, a work-in-progress 3-tesla MRI scanner, and uMI Panvivo, a PET/CT scanner. The uMI Panvivo is a new PET/CT scanner with scalable architecture and an air-cooled compact design. The scanner has 219 per second time-of-flight (TOF) timing resolution, 2.9 mm NEMA spatial resolution, and 181 cps/kBq effective sensitivity, and is designed to provide image clarity and lesion detectability. It has a large boar clearance for patient comfort.

Market Dynamics
Drivers: Rapid adoption of digital and hybrid PET systems is significantly driving the positron-emission tomography (PET) market growth
The rapid adoption of digital and hybrid PET systems is significantly driving the growth of the PET market by enhancing diagnostic capabilities and expanding clinical applications. Digital PET systems offer improved spatial resolution and sensitivity, enabling more accurate detection of small lesions and reducing radiation exposure. Hybrid PET/CT systems provide comprehensive insights into disease processes. Novel product launches by major market players are driving this trend.
For instance, in June 2024, Siemens Healthineers introduced the Biograph Trinion, a high-performance, energy-efficient positron emission tomography/computed tomography (PET/CT) scanner with a wide range of clinical capabilities and a low lifetime operational cost. The scanner’s high-performance PET/CT platform has a new, scalable, air-cooled, digital detector based on lutetium oxyorthosilicate (LSO) crystal elements. This detector delivers high spatial resolution and an ultrafast time-of-flight performance of 239 ps for small lesion detectability and effective sensitivity up to 128 cps/kBq, enabling fast scans and low patient radiation doses.
Additionally, in May 2025, Mahajan Imaging & Labs unveiled North India’s first 128-Slice Digital PET-CT, Omni Legend by GE HealthCare, along with a modern state-of-the-art pathology lab. Similarly, in June 2025, S.L. Raheja Hospital launched AI-enabled Digital Positron Emission Tomography – Computed Tomography (Digital PET CT) scan and 3 Tesla Magnetic Resonance Imaging (3T-MRI) services. In addition, the hospital introduced advanced Neonatal Intensive Care Unit (NICU) and Pediatric Intensive Care Unit (PICU) services to further enhance critical care for infants and children.
Restraints: Competition from alternative imaging modalities is hampering the growth of the market
Competition from alternative imaging modalities is a significant restraint hampering the growth of the positron emission tomography (PET) market, as healthcare providers often rely on other advanced imaging techniques that are more cost-effective or widely available. Modalities such as Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) remain preferred in many clinical settings due to their lower cost, broader accessibility, and absence of radiotracers. For example, MRI is often favored in neurological and musculoskeletal imaging because of its superior soft-tissue resolution, while CT is widely used in cardiology and emergency diagnostics due to speed and availability.
Similarly, Single Photon Emission Computed Tomography (SPECT) competes directly with PET in nuclear cardiology applications, offering lower operational costs despite PET’s superior image quality. A case in point is cardiac imaging, where SPECT continues to dominate because of lower pricing and greater insurance coverage, limiting PET adoption despite the approval of advanced tracers like GE HealthCare’s Flyrcado (2024) for myocardial perfusion imaging. Additionally, cost barriers and the need for radiopharmaceutical infrastructure make PET less accessible in smaller hospitals and emerging markets, prompting reliance on CT or MRI instead. This strong presence of alternative imaging solutions poses a challenge to PET’s wider adoption, slowing down its growth trajectory.

Segmentation Analysis
The global positron-emission tomography (PET) market is segmented based on product type, application, end-user, and region.
Product Type: The hybrid PET systems segment is dominating the positron-emission tomography (PET) market with a 56.81% share in 2024
Hybrid PET systems, particularly PET/CT and PET/MRI combinations, have emerged as the dominant segment in the positron emission tomography (PET) market due to their ability to provide both functional and anatomical imaging in a single scan, significantly enhancing diagnostic accuracy and clinical decision-making. By integrating metabolic information from PET with structural detail from CT or MRI, these systems enable precise tumor localization, staging, and therapy monitoring, which is especially critical in oncology, neurology, and cardiology. The PET/CT segment alone accounted for the largest market share, reflecting its widespread adoption in hospitals and diagnostic imaging centers globally.
Recent product launches further demonstrate the momentum in this segment. For instance, in June 2024, Siemens Healthineers introduced the Biograph Trinion, a high-performance, energy-efficient positron emission tomography/computed tomography (PET/CT) scanner with a wide range of clinical capabilities and a low lifetime operational cost. This new system is designed to be user- and patient-focused as well as a sustainable investment in terms of reduced installation and operational costs and easy, on-site scalability.
