High-resolution computed tomography (CT) measurements of emphysema typically use Hounsfield unit (HU) density histogram thresholds or observer scores based on regions of low x-ray attenuation. Our objective was to develop an automated measurement of emphysema using principal component analysis (PCA) of the CT density histogram. ⋯ We generated an automated emphysema score using PCA of the CT density histogram with a 91% COPD classification rate that showed strong and significant correlations with pulmonary function tests, single HU thresholds, and (3)He magnetic resonance imaging ADCs.

Burnout is a complex phenomenon characterized by emotional exhaustion, social detachment, and feelings of low personal achievement. In this study, we aim to establish the prevalence of burnout among radiology trainees and to explore the factors influencing its development. ⋯ The unique nature of radiology training could mean that traditional assumptions regarding the development of trainee burnout do not necessarily apply. Finances may be an underappreciated influence on resident burnout, and subjective feelings of financial scarcity could outweigh the impact of objective indebtedness. Further study is needed to ensure that the emotional well-being of radiology trainees is optimally supported.
