Nonuniform contrast opacification of vasculature is frequently encountered on thoracic computed tomographic angiography. The purpose of this pictorial essay is to discuss the appearance of, and factors underlying mixing artifacts, which we term "smoke." We provide an approach to distinguish it from pathology including pulmonary embolism, aortic dissection, and thrombus.

The solitary pulmonary nodule (SPN) is a common medical problem for which management can be quite complex. Imaging remains at the center of management of SPNs, and computed tomography is the primary modality by which SPNs are characterized and followed up for stability. This manuscript summarizes the American College of Radiology Appropriateness Criteria for radiographically detected solitary pulmonary nodules and briefly reviews the various imaging techniques available.

Data from the Minnesota Breast Cancer Family Study cohort (n=6,130 women) were used to examine the association of type II diabetes with mammographic percent density and incident breast cancer (BC). Exposures and outcomes were self-reported. The first set of analyses evaluated diabetes (DM) as a risk factor for breast cancer.

Many patient management decisions an otolaryngologist makes every day stem from good patient- and population-based evidence. This paper will explore the topic of population/database research and how these studies are useful. We also examine the current literature on this subject, explore the strengths and weaknesses of these studies and provide information on the practical aspects of performing this type of research.
