“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.

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

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

Photon-counting CT scan of chronic thromboembolic pulmonary hypertension
[Figure 1] Chronic emboli of the pulmonary arterial vessels can result in chronic thromboembolic pulmonary hypertension (CTEPH). Detection and evaluation are challenging with conventional CT because of the size and location of the emboli. Contrast media used to visualize filling defects in the pulmonary vessels can also now be used to extract the distribution within the lung tissue and show the perfusion of the lung. Here, the method was used to visualize the effect of CTEPH and the postintervention outcome. The aim is to remove the fibrotic material that causes the stenosis and occlusions of the pulmonary vasculature. The successful outcome is well visualized here.
