Positron Emission Tomography Market Size

The positron emission tomography market size was valued at around USD 2.1 billion in 2024 and is estimated to grow at 6.1% CAGR from 2025 to 2034. Positron Emission Tomography (PET) is an advanced imaging technique used in medicine to observe metabolic and physiological processes within the body. It provides detailed functional images that aid in diagnosing, monitoring, and managing various diseases.

The PET market is experiencing significant technological advancements through the development of hybrid imaging systems that combine PET with CT or MRI technology. These integrated systems offer improved diagnostic accuracy and are in high demand. For example, in July 2021, GE Healthcare collaborated with Quibim to develop an innovative total-body PET/CT scanner for simultaneous whole-body imaging. This product development strengthens the company’s market position and expands its product offerings, thus driving industry growth.

Technological advancements are broadening PET applications in clinical practice. PET imaging’s role in disease diagnosis and treatment continues to evolve with advancing technology. For instance, time-of-flight PET technology improves image resolution and shortens scan times by calculating photon travel time between the source and detector, enabling faster production of high-quality images. These technological innovations are expected to drive market growth.

Moreover, the growing demand for PET analysis in radiopharmaceuticals is being fueled by several factors, including the rising prevalence of cancer, the increased availability and affordability of PET scanners, and the expanding range of applications for PET in the diagnosis and monitoring of various medical conditions. Additionally, the development of new radioisotopes and radiotracers has further expanded the scope of PET analysis. As a result, these factors are expected to contribute to the continued growth of the market.
