Driver - Increase in Demand for Cancer Monitoring Using PET/CT Systems Market

The management of cancer has evolved to include different modalities of treatment methods, such as chemotherapy, surgery, and radiation therapy. Efficient management requires the accurate evaluation and diagnosis of tumour growth, and PET/CT systems are being extensively used for providing sophisticated images for further assessing the origin of the tumour and the metastatic disease.

PET/CT systems are being increasingly adopted for cancer monitoring around the globe. In a study conducted at a major hospital in the Asian region, which consisted of 98 patients affected with various forms of cancer, it was found that PET-CT systems were successful in diagnosing the presence of cancer in 77% of the cases.

In comparison, a whole-body Magnetic Resonance Imaging (MRI) was able to do so in only 55% of them. Furthermore, the demand for PET/CT systems is being triggered by the growing demand from radiology departments. PET/CT systems can be easily used to perform standalone CT scans. This has further justified the usage of CT as a part of PET/CT systems for justifying the high investments in this technology.

Restraints - High Capital and Operating Costs of PET/CT Infrastructure

A key restraint limiting broader PET/CT adoption is the high financial burden associated with establishing and maintaining hybrid imaging facilities. PET/CT scanners require multimillion-dollar capital investment, and the costs extend beyond equipment to include specialized room construction, radiation shielding, and quality-assurance systems.

Operational expenses further elevate lifetime ownership costs, as providers must manage ongoing service contracts, periodic upgrades, consumables, and radiotracer procurement often sourced from nearby cyclotrons or commercial radiopharmacies.

Staffing requirements add another layer of expense since PET/CT imaging demands training in nuclear medicine physicians, technologists, physicists, and radiation safety personnel. In low- and middle-income countries, constrained healthcare budgets and competing priorities significantly slow technology adoption, with many centers operating aging equipment well past recommended replacement cycles.

Even in developed markets, tight reimbursement frameworks, cost-containment initiatives, and limited capital approvals make it challenging for community hospitals and small imaging centers to justify new installations. These financial pressures collectively hinder market expansion and restrict access to advanced hybrid imaging, particularly outside major urban healthcare hubs.

Opportunity - Rising Adoption of Mobile and Distributed Imaging Models

The increasing push to improve access to advanced diagnostic imaging offers a strong opportunity for mobile PET/CT units and distributed imaging networks. Many secondary hospitals and rural regions continue to face limited availability of hybrid imaging systems, resulting in long travel distances and delayed diagnostic pathways for patients.

Mobile PET/CT units deployed on scheduled routes or through long-term service agreements enable providers to extend high-quality imaging to underserved areas without the burden of building a full on-site facility. Similarly, hub-and-spoke models, where cyclotrons and radiopharmacy services are centralized and scanners are distributed across multiple satellite sites, help optimize asset usage and reduce overall operating costs.

Improvements in system design, including compact high-slice scanners, ruggedized components, and faster setup times, have made mobile deployment more practical and scalable.

Cloud-enabled reporting platforms and remote reading capabilities further support these models by allowing specialists based in tertiary centers to interpret scans performed at distant locations. As healthcare systems prioritize decentralization and equitable access, vendors offering flexible, mobile, and shared-service imaging solutions are well-positioned to capture emerging demand across expanding regional networks.?

By Product Type Insights

High-range slice scanners (<64 slices) are projected to hold the largest share of the PET/CT systems market in 2025, contributing roughly 57%. These systems deliver faster acquisition speeds, broader anatomical coverage, and improved temporal resolution, which are essential for oncology staging, complex treatment planning, and high-throughput diagnostic workflows.

Their ability to visualize small lesions with greater clarity supports more accurate disease assessment, particularly in cancers requiring whole-body imaging. Many high-range models also incorporate advanced features such as ultra-low-dose imaging, iterative reconstruction techniques, and metal artifact reduction, enabling clinicians to achieve high-quality scans while minimizing radiation exposure.

As hybrid applications like PET/CT angiography, cardiac perfusion imaging, and therapy response monitoring continue to expand, the demand for high-performance, high-range scanners remains strong, reinforcing their dominant market position.

By Isotope Insights

Fluorodeoxyglucose (FDG) continues to dominate PET/CT utilization worldwide, accounting for more than 70% of annual PET scan volumes. Its capability to map glucose metabolism makes it indispensable for evaluating a wide range of tumors, inflammatory conditions, and certain neurologic disorders.

Because FDG is included in numerous global clinical guidelines for diagnosis, staging, and treatment response assessment, it remains the primary tracer used in routine oncologic imaging. National audits, including those from Canada and Europe, consistently show that FDG-based oncology scans form the bulk of PET/CT procedures, underscoring its deep integration into standard care pathways.

Although new isotopes such as Gallium-68 PSMA, Gallium-68 DOTA derivatives, and emerging fluorinated tracers are gaining momentum particularly in prostate cancer, neuroendocrine tumors, and targeted Theranostics they currently serve specialized applications rather than replacing FDG.

As a result, PET/CT system configurations, dose management protocols, and workflow designs continue to be optimized around FDG, preserving its central role in clinical and operational decision-making.
