ESOC 2026 | Growing clinical relevance of photon-counting CT in stroke imaging
Linda Jacobi-Postma, MD, PhD, Maastricht UMC+, Maastricht, Netherlands, discusses the growing clinical relevance of photon-counting CT in stroke imaging, highlighting its potential to improve CT angiography (CTA) resolution and reduce the need for invasive procedures such as digital subtraction angiography in patients with aneurysms. This interview took place at the 12th European Stroke Organisation Conference (ESOC) in Maastricht, The Netherlands.

Transcript
If you look now, photon counting CT, there are a few hospitals who have photon counting CT. It’s still expanding, but we just have one vendor. I think when we are 10 or 20 years ahead, every hospital will have a photon counting CT. So when we started three years ago, there were only two photon counting CTs in the Netherlands, and now there are already a dozen of photon counting CTs. So we’re really looking into what part of the photon counting CT is for the benefit of the patient...
If you look now, photon counting CT, there are a few hospitals who have photon counting CT. It’s still expanding, but we just have one vendor. I think when we are 10 or 20 years ahead, every hospital will have a photon counting CT. So when we started three years ago, there were only two photon counting CTs in the Netherlands, and now there are already a dozen of photon counting CTs. So we’re really looking into what part of the photon counting CT is for the benefit of the patient. So non-contrast CT probably is not the benefit. I think CTA is the way to go, and the patients will have the benefit for that. Because if you, for example, have a patient with an aneurysm, now the patient will have a DSA for the configuration of the aneurysm, for the vessel sprouting from the aneurysm to make your treatment decision. But if you just can do it with photon counting CT, this will make the DSA not necessary anymore. So that’s really the benefit for the patients, I think.
