“…Focal diseases are localized to a specific area, e.g., lung nodules or pulmonary embolism [2], while diffuse diseases, such as interstitial lung disease (ILD) and most pleural diseases, are more widespread across the lungs and pleura [3]. Diffuse diseases share common challenges in radiological evaluation: they all cover an extended number of CT slices in thoracic CT scans, making their burden notoriously hard to quantify [4,5,6,7]. Standardizing radiological methods to evaluate the extent of the patient's disease is therefore challenging, often in contrast with the clinical practice, which requires evaluation criteria that are easy to use, time-efficient, and cost-effective [8].…”
