Chronic obstructive pulmonary disease is a heterogeneous disease characterized by small airway abnormality and emphysema. We hypothesized that a voxel-wise computed tomography analytic approach would identify patterns of disease progression in smokers. ⋯ A voxel-wise longitudinal PRM analytic approach can identify patterns of disease progression in smokers with and without chronic obstructive pulmonary disease.

We aimed to determine the utility of various diffusion parameters obtained from monoexponential, biexponential, and stretched exponential diffusion-weighted imaging (DWI) models in differentiating tumor stage and grade of bladder cancer. ⋯ Biexponential and stretched exponential DWI models may provide more parameters in staging and grading bladder cancers and show a slight difference between DDC and ADC values in staging bladder cancers. These two DWI models, as well as the monoexponential models, were very helpful in staging and grading bladder cancers.

To determine independent contribution of each prostate multiparametric magnetic resonance imaging (mpMRI) sequence to cancer detection when read in isolation. ⋯ When prostate mpMRI sequences are interpreted independently by multiple observers, DWI achieves highest sensitivity and CDR in transition zone and peripheral zone. T2W and DCE MRI both add value to detection; mpMRI achieves highest detection sensitivity when all three mpMRI sequences are positive.

We examined female representation on editorial boards of four prominent radiology journals. We compared editorial board representation to female academic radiology career advancement and the proportion of female authorship in three journals over four decades. ⋯ Female representation on editorial boards has increased over time, but still lags behind increases seen in female first authorship in radiology journals and radiology faculty appointments over the last four decades. There was no female editor-in-chief during the study period.

To analyze the pattern and longitudinal evolution of honorary authorship in major radiology journals. ⋯ There has been little variation in the perception of honorary authorship among first authors of original research articles in radiology. The suggestion of adding an author and having coauthors performing only nonauthorship tasks are the two most important risk factors for honorary authorship. Our findings indicate that a prolonged course of transformation of current cultural norms is required to decrease honorary authorship.
