Professor Jiri Ferda, MD, PhD, talks about the initial steps with the new technology in both research and clinical practice.

When did you start using photon-counting CT and what were your expectations?

Looking at oncology specifically, what were the limitations of traditional CT scanners?

Where and how has photon-counting been able to overcome these limitations?

Jiri Ferda reports an improved tumor delineation with photon-counting CT.

How do improved image contrast and higher spatial resolution affect your diagnoses?

Which patients benefit in particular, also with regard to lower radiation dose and less use of contrast media?

How and in which cases are you using the spectral information now available from a single scan?

How does the availability of monoenergetic images for every scan assist physicians in making a diagnosis or follow-up?

How are you using photon-counting for standard examinations? How does the technology perform in these cases?

Could you please describe one or two patient cases where photon-counting has been particularly helpful?

How do you see the role of CT evolving in your specialty with photon-counting technology?

Is there anything else you would like to mention to our readers?
