The global PET-CT scanning services industry is at the forefront of a diagnostic revolution, merging the functional precision of Positron Emission Tomography with the anatomical clarity of Computed Tomography. As of 2025, the market has reached a valuation of USD 19.91 billion, serving as a critical pillar in modern precision medicine.
Market Overview and Size
Driven by the rising global burden of chronic diseases and the integration of artificial intelligence (AI), the PET-CT scanning services market is entering a phase of sustained expansion. The industry is projected to grow from its current 2025 valuation to USD 30.39 billion by 2033, reflecting a steady CAGR of 5.6%.
This growth is largely attributed to the shift toward outpatient care and the increasing accessibility of oncological imaging, which remains the primary revenue generator. The transition from traditional analog systems to digital PET-CT scanners has significantly enhanced lesion detectability while reducing patient radiation exposure, further encouraging clinical adoption.
