Reachable Buyer Map

Prepared for Scott Conry · Curium · The United States layer · August 2026
Curium's own site describes serving hospital departments, nuclear and PET pharmacies and radiopharmacies. This map counts the United States layer of that market: how each part of it registers itself, who signs inside it, and roughly how many organizations sit there. It describes the market rather than your business, and there is nothing to buy at the end of it.
Nuclear medicine practices and departments
The core of the market and one of the smallest countable layers in US medicine. In this segment the decision usually involves three people who rarely sit in the same room: the physician who chooses the agent, the technologist who has to handle it, and the pharmacy or materials office that signs for it.
Who signs: nuclear medicine medical director, chief of radiology, director of imaging services, director of pharmacy, materials management lead.
1,250 to 1,400
US organizations registered under a nuclear medicine classification
Nuclear cardiology
The highest-volume routine use of a radiopharmaceutical in the country, and the segment most exposed to a supply interruption, because the schedule is booked before the dose is in the building. Buying here is closer to a standing arrangement than a purchase decision.
Who signs: cardiology practice medical director, nuclear laboratory director, practice administrator, and in hospital-employed groups the service line director.
650 to 725
US organizations registered under a nuclear cardiology classification
Nuclear radiology
Registered separately from nuclear medicine even though the work overlaps heavily. That separation is the practical point of this page: a pull built on one classification always misses part of the same market, and the missed part is not the small part.
Who signs: chief of radiology, imaging director, radiology practice president, and at independent centers the owner or administrator.
675 to 750
US organizations registered under a nuclear radiology classification
Radiation oncology
The therapy side, and the largest countable segment on this page. The route in is different from diagnostics: capital, shielding, licensing and physics sit in the conversation from the first meeting, so the cycle is longer and the buying group is wider.
Who signs: radiation oncology medical director, medical physics lead, cancer center administrator, chief medical officer.
2,500 to 2,700
US organizations registered under a radiation oncology classification
Combined imaging and therapy
A small and specific classification, and a useful signal rather than a large segment. An organization that registers it is telling the register that diagnostic and therapeutic work happen under one roof, which is a shorter path than selling the two sides separately.
Who signs: service line director, medical director, director of pharmacy, cancer center administrator.
125 to 150
US organizations registered under a combined nuclear imaging and therapy classification
Radiopharmacies
The segment where the register understates the market badly. Most radiopharmacies operate under a parent organization's identifier or bill through the hospital they serve, so only a fraction enumerate under their own classification. The distribution layer is materially larger than the figure alongside, and it has to be identified by name rather than pulled from a list.
Who signs: pharmacy director, general manager, regional operations manager, and at independent sites the owner.
Roughly 40 registered under their own classification
the wider US radiopharmacy network is not separately enumerated anywhere public

Where the openings are

1
Across all six classifications the register holds roughly 4,400 distinct US organizations. That is fewer than the tiles added together, because one organization often registers under more than one of them. It is a small enough institutional layer to work by name rather than by campaign, which is unusual and worth using.
2
The buyer here is a role, not an account. Medical director, imaging director, director of pharmacy, cancer center administrator. Those seats turn over, and a new one reopens supply and formulary questions that looked settled. A channel built on named roles catches that moment. An account-led one hears about it after the decision.
3
Two of the six only surface if you go looking. Nuclear radiology registers separately from nuclear medicine, and radiopharmacies mostly do not register under their own classification at all. Anyone pulling one classification off the shelf reaches part of this market and calls it the market.
4
Diagnostic and therapeutic buyers are not the same people. The diagnostic side sits with imaging and cardiology and moves on schedule and supply. The therapeutic side sits with oncology, physics and licensing and moves on capital and program readiness. One audience will not carry both, and the segment that registers for both is the smallest one on this page.
Built from the public federal provider register, organization records only, pulled 17 August 2026 and deduplicated by provider identifier. Counts are banded deliberately. The unit is the registered organization, so a multi-site group appears once or many times depending on how it chose to enumerate. Classification codes are self-selected by the organization, which is why the same activity surfaces under more than one heading. Individual clinicians are excluded throughout.
