Novel Logistic Regression Model of Chest CT Attenuation Coefficient Distributions for the Automated Detection of Abnormal (Emphysema or ILD) Versus Normal Lung.
We evaluated the role of automated quantitative computed tomography (CT) scan interpretation algorithm in detecting interstitial lung disease (ILD) and/or emphysema in a sample of elderly subjects with mild lung disease. We hypothesized that the quantification and distributions of CT attenuation values on lung CT, over a subset of Hounsfield units (HUs) range (-1000 HU, 0 HU), can differentiate early or mild disease from normal lung. ⋯ We demonstrated the potential usefulness of this novel quantitative imaging analysis method in discriminating ILD and/or emphysema from normal lungs.

Learner assessment in medical education has undergone tremendous change over the past two decades. During this time frame, the concept of Entrustable Professional Activities (EPAs) was introduced to guide the faculty when making competency-based decisions on the level of supervision required by trainees. EPAs are gaining momentum in medical education as a basis for decisions related to transitioning from residency training to clinical practice. The purpose of this article is twofold: (1) define EPAs for radiology (EPA-R) and (2) illustrate radiology-specific examples of these EPAs. ⋯ EPAs offer an opportunity to improve our approach to training by increasing our focus on how we provide appropriate supervision to our residents and assess their progress. In this work, through suggested lists and vignettes, we have attempted to establish the framework for further discussion and development of EPA-Rs.
