Summary: The differential diagnosis of idiopathic interstitial pneumonias (IIPs) with thin-section computed tomography (CT) is an important and particularly difficult task in clinical radiology. The distinction between the two most common entities, idiopathic pulmonary fibrosis (IPF) and nonspecific interstitial pneumonia (NSIP) is especially important because these two entities have substantially different prognoses and  usually require different treatment.

This project will create an automated computer-aided diagnosis (CAD) system with two main aims: 1) To differentiate between the textural expression of usual interstitial pneumonia (UIP, the histopathological counterpart of IPF) and NSIP in a fully automated fashion while providing increased sensitivity/specificity over today's differential diagnosis; 2) To allow early diagnosis by performing spatiotemporal analysis of disease progression, yielding novel insights into disease formation.

The computational framework we will develop during the project first segments the lung in the CT volume, then computes and selects relevant three-dimensional texture features, and, subsequently differentiates automatically between IPF/UIP and NSIP. The change in the lung's interstitial architectures is assessed by a classification pipeline based on three-dimensional features that represent the texture sub-types e.g., ground-glass opacities, reticular opacities, honeycombing, etc.). The diagnostic power of the system is improved by machine learning approaches, which are used for the automatic selection of the associated texture features. This leads to a classification of IPF/UIP versus NSIP based on an optimal differentiation between the texture sub-types.

Tracking the local texture changes between the first examination and all follow-up examinations will yield mathematical models that precisely describe the spatiotemporal progression of the disease, allowing the study of trends within the cohort. The resulting automatic, quantitative analysis of the spatiotemporal progression of IIPs will provide new insights into the disease course characteristics.
