PET imaging procedures in the U.S. increased 12.2% year-over-year in 2024, according to IMV Medical Information Division’s newly released 2025 PET Market Summary Report.
The findings highlight steady demand growth alongside limited expansion in installed imaging capacity.
The Palo Alto, California-based firm reported an 8.2% increase in PET scans performed per installed fixed PET/CT system over the same period, suggesting that much of the additional volume was managed with existing infrastructure rather than new system installations.

“Sites with a fixed PET/CT system averaged 336 scans per physician annually,” said Davin Korstjens, director of market intelligence at IMV. “This number varies significantly by facility size—from 119 scans at hospitals with fewer than 200 beds, to 567 at hospitals with more than 400 beds.”
Independent imaging centers averaged 285 scans per physician per year, while hospital-owned centers averaged 260.
In terms of staffing, general radiologists interpreted PET scans at 69% of surveyed sites, followed by nuclear medicine physicians at 51%, and cardiologists or nuclear cardiologists at 11%. The leading referrers for PET procedures included medical oncologists, radiation oncologists, and pulmonologists.
In 2023, the total volume of PET scans increased 10.2% year over year,
according to last year's report.
Despite the rise in volumes, scheduling delays have persisted. Forty percent of facilities reported outpatient wait times of eight or more days for nonemergency scans, a rate unchanged from the previous year but up sharply from 19% in 2019.
The report suggests that without expansion in PET imaging capacity, current resources may be stretched further as demand continues to rise.
The
2025 PET Market Summary Report draws on responses from 509 radiology administrators and clinicians collected between February 2024 and January 2025. It includes insights on equipment vendors, service providers, operational metrics, and future purchase plans. Vendors examined in the report include GE HealthCare, Siemens, Philips, United Imaging, and others.
