  • Halfmann, M. et al. Pre-interventional AI-supported automated lung parenchyma quantification predicts post-interventional complications in CT-guided lung biopsies (2023)
    • Results: AI-based quantification of lung texture has potentially a predictive value for complications. Greater amount of pre-interventional consolidations (p=0.03) and smaller lesion size (p=0.04) were predictors for post-interventional pneumothorax.

MILD study, Prof. Kaveh Akbari: a prospective study on comparing information from CT vs. MRI for fibrosis patients

In the imaging diagnostics of interstitial lung diseases, the study situation indicates that MRI can provide additional information compared to CT – for example with regard to the differentiation of inflammatory versus fibrotic genesis, early diagnosis of lung involvement in the context of collagen vascular disease or also with regard to the quantification of the disease during the course of therapy.

With the MILD study they want to analyze these points in a prospective setting. They will also examine to what extent the quantitative CT analysis using contextflow can also provide this additional information.

Study: Lung radionomics vs. lung function test: quantitative profiling for treatment response vs. manual lung pattern scores and lung function for 6/12/24 months.
