The global diagnostic imaging market is projected to increase from USD 26.5 billion in 2026 to USD 33.2 billion by 2031, representing a 4.6% compound annual growth rate, according to Wissen Research. Expansion is being supported by rising chronic disease prevalence, population aging and demand for earlier, more accurate diagnosis. AI-assisted imaging, 3D/4D visualization and portable devices are improving image quality, radiology workflows and access across hospitals, outpatient clinics, emergency departments and rural facilities. The report identifies deep learning reconstruction, which processes noise during image acquisition, as a major technology shift. GE HealthCare's Sonic DL sequence enables complex multi-sequence brain and joint MRI protocols to be completed in under 15 minutes. More than 1,100 AI-enabled devices have been cleared by the U.S. FDA, with radiology accounting for the largest share of clearances. Cloud-based PACS (medical image storage and distribution systems) and teleradiology are supporting remote reporting across multi-site networks, while photon-counting CT and hybrid imaging are improving resolution and reducing radiation exposure. Growth is constrained by reimbursement pressure, equipment costs, radiologist shortages and cybersecurity concerns. The Centers for Medicare & Medicaid Services introduced a 2.5% work relative value unit reduction across roughly 7,700 diagnostic and procedural codes in the 2026 Medicare Physician Fee Schedule, while new combined head and neck CTA codes have reduced global payments by as much as 30.8%. X-ray held the largest modality share in 2025, North America led by region, and Asia-Pacific was the fastest-growing market. Wissen Research says manufacturers and providers must balance technology investment with tighter reimbursement while expanding outpatient, portable and underserved-care access.
