Chronic obstructive pulmonary disease (COPD) is described as airflow limitation that is not fully reversible. Quantitative assessment of structural changes within the lung that are responsible for this airflow limitation has relied on the examination of tissue obtained from surgical or postmortem specimens. ⋯ Another application of this approach is that it potentially allows phenotyping of individuals who predominately have emphysema or small-airway disease, which may be important for the evaluation of pathogenesis and prescription of treatment options. This review describes some of these CT techniques for quantitative assessment of lung structure.

An image registration method was developed to automatically correct motion artifacts, mostly from breathing, from cardiac cine magnetic resonance (MR) images. ⋯ The novel method was capable of robustly and accurately correcting motion artifacts from cardiac cine MR images.

The purpose of this project was to further understand the academic radiologist's clinical workload with comparison to the prior studies in the past decade. This updated data is very important in determining faculty staffing requirements. ⋯ Clinical workload as measured by RVU/FTE and adjusted RVU/FTE are very useful for determining optimal staffing in subspecialty sections and in the department as a whole. The workload continues to increase, but more in examination complexity than in numbers of procedures overall.

Comparative Study
Accuracy of computed tomography attenuation values in the characterization of pleural fluid: an ROC study.
To assess the accuracy of computed tomography (CT) in characterizing pleural fluid based on attenuation values. ⋯ Although the mean attenuation of exudates is significantly higher than transudates, the clinical use of CT numbers to characterize pleural fluid is not recommended, as their accuracy is only moderate. Moreover, there is a notable overlap in attenuation values between transudates and exudates for a majority of effusions.
