The U.S. diagnostic imaging services market size accounted for USD 169.4 billion in 2025 and is predicted to touch around USD 283.92 billion by 2035, growing at a CAGR of 5.3% from 2026 to 2035.A strong shift from hospitals to outpatient clinics, growth in minimally invasive surgeries, and adoption of high-speed automated imaging are the primary growth drivers for the diagnostics sector in the U.S.

U.S. Diagnostic Imaging Services Market Scope Statical Scope

The U.S. Department of Health and Human Services (HHS) launched a major federal initiative that aims to address the management of medical images across different healthcare systems. On the other hand, the U.S. Department of Commerce launched a federal investigation into the import of essential medical imaging devices. The veterans in rural and underserved areas have access to advanced diagnostics like CT scans and MRI scans. The federal government has introduced stricter documentation and auditing standards.

However, the Centers for Medicare and Medicaid Services (CMS) is making efforts to integrate AI-assisted imaging technologies. This program focuses on adopting deep learning image analysis tools to enhance diagnostic accuracy and reduce scan turnaround times. The CMS also presented Medicare physician fee schedule updates and set the reimbursement rates for imaging procedures like MRI, CT, and PET. Moreover, the Department of Veterans Affairs (VA) announced the expansion of its (remote) tele-radiology services that connect regional networks.

U.S. Diagnostic Imaging Services Market Share, By Modality, 2025 (%)

• X-ray - The X-ray segment dominated the market in 2025, with a share of 31%, owing to a robust presence of advanced imaging centers and high adoption rates of cloud-based enterprise imaging and AI platforms. The modern X-ray services are beneficial in terms of AI-enhanced diagnostic precision, ultra-fast results, smart triaging, and eco-friendly workflows. The seamless integration with cloud platforms and teleradiology allows the transmission and review of images by remote specialists instantly.
• MRI Scans - The MRI scans segment held a 26% share and is expected to grow in the coming years, driven by the generation of safe images via radio waves and magnetic fields for vulnerable populations, pediatric patients, and people requiring long-term chronic disease monitoring. High-V MRI imaging enables implant-friendly imaging, which minimizes distortion and artifacts. It also allows safe scanning for a broader patient base.
• CT Scans - The CT scans segment held a 18% share and is expected to grow in the coming years due to the capabilities of advanced CT scans, which allow them to deliver full-color tissue differentiation, ultra-low dose via AI optimization, and more. They are also enabled to perform tests within a few seconds and are used in predictive risk stratification and screening. The core diagnostic clinical applications of CT scans revolve around oncology, cardiology, and trauma care.
• Ultrasound - The ultrasound segment held a 14% share and is expected to grow in the coming years, driven by the consumption of less electrical energy by ultrasound in both its production and active operation phases than heavy cross-sectional modalities like CT and MRI. Diagnostic imaging providers favor ultrasound over radiation-heavy modalities. They aim to reduce institutional costs and decrease departmental greenhouse gas emissions.
• Nuclear Medicine Scans - The nuclear medicine scans segment held a 11% share and is expected to grow in the coming years due to AI-assisted quantification and dose optimization.

U.S. Diagnostic Imaging Services Market Share, By End Use, 2025 (%)

• Hospitals - The hospitals segment dominated the market in 2025, with a share of 68%, supported by high patient volumes, advanced imaging infrastructure, and the availability of specialized radiology departments. Hospitals remain hubs for complex and high-volume modalities, including critical care support and financial support. Hospitals possess capital resources, heavy infrastructure, and specialized talent required for complex clinical interventions.
• Diagnostic Imaging Centers - The diagnostic imaging centers segment held a 32% share and is expected to grow in the coming years, driven by growing demand for specialized, cost-effective, and outpatient imaging services. This growth is driven by a global shift toward ambulatory care. These specialized centers lower diagnostic costs and serve as the testing platform for advanced medical technology.

Competitive Landscape

The top diagnostic imaging equipment manufacturers across North America are GE Healthcare, Siemens Healthineers, Philips Healthcare, Canon Medical Systems, and Hologic, Inc.
