Dual-Energy Spectral Imaging Draws Interest from CT Buyers



In 2022, the main priorities of the CT departments cover a range of key topics. The highest rated priority is improving patient satisfaction with their CT experience. This is followed by two factors related to hospital staff: meeting the needs of referring physicians and improving staff satisfaction and morale.

The next factor focuses on improving the department’s workflow and productivity. Another patient-related factor – improving the ability to reduce radiation dose to patients – rounds out the top 5 priorities for CT services in 2022.

When it comes to factors influencing the future prospects of IT departments, the top scorers indicate that technology and capacity needs are met for more than half of respondents. This is confirmed by 67% of respondents who agree that current CT scanner technology meets the clinical and throughput needs of their CT department, as well as 58% of sites who agree that the department’s CT capacity is sufficient to meet the volumes of expected patients over the next few years.

Strong Buyer Interest

However, the development of spectral, dual-energy and dual-source systems has generated significant buyer interest, with 38% of all systems planned for purchase featuring this technology. When looking only at the largest hospitals with over 400 beds, this percentage jumps to 58% of planned CT systems with these advanced capabilities.

According to the survey, the impact of the COVID-19 pandemic on CT departments peaked in 2021 and, at the time of the survey, is at the lowest level since 2020. The peak impact occurred in 2021 with 70% of departments experiencing one or high of the pandemic and an average impact rating of 7.3 out of 10. Current impact at the time of the survey in mid-2022 indicates that 34% of sites continue medium or high impact with an average score of 4.9 out of ten.

Estimated annual CT procedure volumes for 2022 are showing slow year-over-year growth, due to increased non-hospital procedure volumes. CT procedure volumes are expected to slowly increase by 0.09% in 2022 compared to 2021. This follows a robust growth rate of 15.7% in 2021 compared to 2020. Hospital-based procedures, while continuing to account for the bulk of overall procedure volume, have slightly decreased by -0.5% since 2021. Non-hospital procedures are up 8% year-over-year and are driving the most gains.

Looking to the end of 2022, 72% of CT sites expect their full-year CT procedure volume to increase from 2021, 17% expect it to remain at the same level, and 9% expect a decrease. Small hospitals (

Overall, 51% of sites plan to purchase a scanner between 2022 and 2025. Mid-sized hospitals are the most likely to plan a purchase, with 49% planning to purchase a scanner. Independent imaging centers are the least likely to plan a purchase, with only 15% planning a purchase.

Looking only at hospitals, purchase intent fell 3 percentage points to 31% of sites planning to buy, compared to 34% in the previous 2021 study. This decline was due to decreases in hospitals with less than 200 beds and more than 400 beds, reflecting increased uncertainty in procurement plans and partially offset by increases in hospitals with 200 to 399 beds.

When it comes to original equipment manufacturers (OEMs) most considered for CT’s next purchase, GE HealthCare takes the top spot with 65% of sites mentioning them, followed closely by Siemens Healthineers at 62%. . Canon Medical Systems is third with 31%, followed by Philips fourth with 27% and Fujifilm Medical Systems which completes the top 5 with 5%.

In 2022, CT services are open on average 12.1 hours per weekday per site and 14.9 hours per weekend per site, for scheduled CT procedures. Across a range of bed sizes, 71% to 85% of hospitals are open more than 9 hours per weekday, compared to 35% of independent imaging centers. On weekends, across a range of bed sizes, 41% to 76% of hospitals are open for an hour or more, compared to 28% of independent imaging centers.
