“Photon-counting CT will become the new standard in chest imaging”

In pulmonology, photon-counting computed tomography (CT) enables physicians to precisely evaluate function thanks to highly detailed spectral maps.

Professor Frank Wacker, MD1, and Professor Jens Vogel-Claussen, MD1, report their experiences in clinical practice.

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


Frank Wacker likes the dose efficiency of photon-counting CT.

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

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

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


Jens Vogel-Claussen sees the potential of photon-counting CT in lung cancer screening.

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?

Photon-counting CT scan of chronic thromboembolic pulmonary hypertension

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?
