Comparative Study
Reliability and validity of soft copy images based on flat-panel detector in pneumoconiosis classification: comparison with the analog radiographs.
The aim of this study was to evaluate the reliability and validity of soft copy images based on flat-panel detector of digital radiography (DR-FPD soft copy images) compared to analog radiographs (ARs) in pneumoconiosis classification and diagnosis. ⋯ DR-FPD soft copy images showed accurate and reliable results in pneumoconiosis classification and diagnosis compared to ARs.

Randomized Controlled Trial
Comparison of 3D phase-sensitive inversion-recovery and 2D inversion-recovery MRI at 3.0 T for the assessment of late gadolinium enhancement in patients with hypertrophic cardiomyopathy.
To compare free-breathing three-dimensional (3D) phase-sensitive inversion recovery (PSIR) with breath-holding two-dimensional (2D) IR sequences to determine which is better for detecting and characterizing myocardial late gadolinium enhancement (LGE) in hypertrophic cardiomyopathy (HCM) patients. ⋯ Three-dimensional PSIR sequence yields higher image contrast, better image quality, and greater detection ability for LGE lesions than 2D-IR sequence.

The aim of this study was to assess the repeatability and internal consistency of flow measurements in the renal arteries and pararenal aorta with the use of standard two-dimensional (2D) and novel four-dimensional (4D) phase contrast (PC) magnetic resonance imaging (MRI). ⋯ The 2D and 4D techniques demonstrated strong repeatability and internal consistency of flow measurements in the renal arteries and pararenal aorta.

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.
