Lungenkrebsscreening: neue Horizonte
Lungenkrebs ist die häufigste Krebstodesursache weltweit. In den frühen, symptomlosen Stadien ist eine kurative Behandlung möglich, allerdings wird die Erkrankung oft zu spät diagnostiziert.

Open AccessEffect of CFTR modulator therapy with elexacaftor/tezacaftor/ivacaftor on pulmonary ventilation derived by 3D phase-resolved functional lung MRI in cystic fibrosis patients
To investigate whether 3D phase-resolved functional lung (PREFUL)-MRI parameters are suitable to measure response to elexacaftor/tezacaftor/ivacaftor (ETI) therapy and their association with clinical outcomes ...

Open AccessAssociation of radiological lung pattern and respiratory mechanics with potential for lung recruitment in patients with COVID–ARDS: a retrospective cohort study
The ventilatory management of COVID–ARDS is controversial, especially with regard to the different subtypes and associated PEEP titration. A higher PEEP may be beneficial only in patients with potential for lu...

Open AccessIncreased regional ventilation as early imaging marker for future disease progression of interstitial lung disease: a feasibility study
Idiopathic pulmonary fibrosis (IPF) is a disease with a poor prognosis and a highly variable course. Pathologically increased ventilation—accessible by functional CT—is discussed as a potential predecessor of ...

Article
Röntgen-Thorax: Durchführung und Indikationen
Die Röntgenübersichtsaufnahme des Thorax ist ungeachtet ihrer mehr als 100-jährigen Geschichte immer noch eine wichtige Technik, um wesentliche Pathologien von Lunge, Herz und Gefäßen schnell und dosissparend ...

Article
Open AccessQuantification of dual-energy CT-derived functional parameters as potential imaging markers for progression of idiopathic pulmonary fibrosis
The individual course of disease in idiopathic pulmonary fibrosis (IPF) is highly variable. Assessment of disease activity and prospective estimation of disease progression might have the potential to improve ...

Article
Open AccessThe current status and further prospects for lung magnetic resonance imaging in pediatric radiology
Lung MRI makes it possible to replace up to 90% of CT examinations with radiation-free magnetic resonance diagnostics of the lungs without suffering any diagnostic loss. The individual radiation exposure can t...

Cardio-pulmonary MRI for detection of treatment response after a single BPA treatment session in CTEPH patients
Chronic thromboembolic pulmonary hypertension (CTEPH) can be treated with balloon pulmonary angioplasty (BPA) in inoperable patients. Sensitive non-invasive imaging methods are missing to detect treatment resp...

Airway remodelling in the transplanted lung
Following lung transplantation, fibrotic remodelling of the small airways has been recognized for almost 5 decades as the main correlate of chronic graft failure and a major obstacle to long-term survival. Mai...
