Overview
New York, NY – July 22, 2025 – The Global Computed Tomography Market size is expected to be worth around USD 9.1 Billion by 2033, from USD 4.4 Billion in 2023, growing at a CAGR of 7.6% during the forecast period from 2024 to 2033.
Computed Tomography (CT) has revolutionized medical imaging, providing detailed, cross-sectional images of the body’s internal structures. This non-invasive diagnostic tool, first introduced in the early 1970s, uses X-ray technology in conjunction with computer processing to produce high-resolution images, enabling healthcare professionals to diagnose a wide range of conditions with greater precision.
CT scans have become indispensable in modern medicine, aiding in the detection of diseases such as cancer, heart conditions, and trauma injuries. The technology works by rotating an X-ray source around the body and capturing multiple images from different angles. These images are then processed to create a comprehensive, three-dimensional view of the area being examined. This allows for a more accurate diagnosis compared to traditional X-ray methods.
Recent advancements in CT technology have focused on improving image quality while reducing radiation exposure. Innovations like multi-slice CT scanners allow for faster scans and improved resolution, significantly enhancing diagnostic capabilities. Moreover, artificial intelligence (AI) integration in CT imaging systems is helping to automate image interpretation, improve diagnostic accuracy, and streamline workflows.
As healthcare continues to evolve, the role of CT technology remains vital in improving patient outcomes, supporting early disease detection, and guiding treatment decisions. With ongoing developments, CT imaging promises to continue enhancing diagnostic precision in clinical practice.

High-end slice CT scanners, such as the Siemens 700 Slice, offer fast scanning speeds and a larger imaging area, making them ideal for patients with arrhythmia, pediatric patients, and obese individuals. Cone Beam CT (CBCT) is expected to experience the fastest growth due to its versatility, lower radiation doses, and effectiveness in dental, orthopedic, and ENT applications.
- Application Analysis: In 2023, oncology held the largest share of the global CT market, capturing 26.80% of the revenue. CT scans are critical for detecting tumors, assessing their size and location, and monitoring the effectiveness of treatments. In oncology, high-resolution CT helps oncologists make informed decisions regarding surgery, radiation, and chemotherapy. The cardiology segment is projected to grow the fastest, driven by advancements in cardiac CT technology that provide detailed imaging of the heart and blood vessels, improving the early detection of coronary artery disease and other cardiovascular conditions.
- End User Analysis: Hospitals dominated the CT market in 2023, holding more than 38% of the market share. The demand for advanced diagnostic technologies in hospitals is increasing as they improve patient throughput and diagnostic accuracy. Diagnostic centers also accounted for a substantial market share, driven by growing outpatient care demand. Additionally, specialized clinics and research facilities are adopting CT for advanced research and treatments, with increasing adoption rates expected due to advancements in technology and the integration of artificial intelligence in imaging processes.

Regional Analysis
North America leads the global Computed Tomography (CT) market, holding a dominant market share of 33.4% in 2023. This growth can be attributed to the significant increase in healthcare spending and the presence of a well-established healthcare infrastructure. According to data from the Centers for Medicare & Medicaid Services, healthcare expenditures in the United States grew by 4.6% in 2018, reaching USD 3.6 trillion, or approximately USD 11,172 per person. Healthcare spending in the U.S. also accounts for nearly 18% of the nation’s GDP.
Meanwhile, the Asia-Pacific region is expected to experience the second-fastest growth in the CT market. This is driven by the large, undiagnosed patient population, rising disposable incomes, rapid urbanization, and growing awareness of the importance of early diagnosis for chronic diseases. Additionally, the region has seen significant advancements in the adoption of medical imaging technologies, further fueling its market expansion.
Emerging Trends
- Rapid Growth in Emergency Department Use: Computed tomography (CT) use in U.S. emergency departments for patients with chest symptoms rose from 2.6% of visits in 2001 to 13.2% in 2007, representing an average annual growth rate of 28.1% during that period. This surge reflects broader adoption of CT for rapid diagnosis in acute care settings.
- High Annual Exam Volumes with Shifting Protocols: Approximately 58±9 million CT examinations are performed each year in the United States. Of these, 54% use axial (step and shoot) scanning and 46% use helical (spiral) scanning, indicating a near even split as facilities balance throughput and image quality.
- Expansion of Low Dose Screening Programs: Low dose CT (LDCT) has been widely adopted for lung cancer screening. The U.S. Preventive Services Task Force recommends annual LDCT for adults aged 50–80 with a ≥20pack year smoking history who currently smoke or quit within the past 15 years.
- Growth of Virtual Colonoscopy: CT colonography also known as virtual colonoscopy is increasingly used in colorectal cancer screening. This technique uses CT images to create a full colon view on a computer screen, facilitating noninvasive detection of polyps and early-stage cancers.
- Emphasis on Radiation Dose Monitoring and Reduction: Federal state partnerships such as the FDA’s Nationwide Evaluation of X ray Trends (NEXT) program regularly collect and analyze patient radiation dose data across U.S. CT facilities, driving initiatives to optimize protocols and minimize exposure.
- Pediatric Dose Risk Research Initiatives: Large international studies like the European EPI CT cohort are investigating long term health risks from pediatric CT scans. This project aims to enroll about one million young patients across multiple countries to inform age appropriate dose reduction strategies.
Use Cases
- Pulmonary Embolism Evaluation in the ED: CT angiography has become the standard for suspected pulmonary embolism in emergency care. By 2007, 13.2% of ED visits for chest pain, shortness of breath, or hemoptysis included CT imaging, supporting early detection and treatment planning.
- Lung Cancer Screening in High Risk Adults: Annual LDCT scans are performed on adults aged 50–80 with significant smoking histories. Under CMS coverage, eligible beneficiaries receive yearly LDCT, improving early lung cancer detection rates and reducing mortality in this population.
- CT Colonography for Colorectal Cancer: Virtual colonoscopy via CT colonography is used to screen asymptomatic individuals. The method produces detailed colon images, enabling detection of polyps ≥6mm in diameter with high sensitivity, and is offered as an alternative when optical colonoscopy is contraindicated.
- Broad Diagnostic Applications: CT exams totaling some 58±9 million annually are routinely used to detect tumors, infections, blood clots, and internal bleeding. Their high spatial resolution and rapid acquisition make them indispensable in trauma, oncology, and infectious‑disease management.
- Attenuation Correction in Hybrid Imaging: In PET/CT systems, CT data are used for attenuation correction, reducing overall scan time and improving lesion localization in oncology and cardiology. This integration enhances diagnostic accuracy and patient throughput.
