Multicenter Study
Does distance matter? Effect of having a dedicated CT scanner in the emergency department on completion of CT imaging and final patient disposition times.
To evaluate whether presence of a CT scanner in the emergency department (ED) improves ED workflow by decreasing time between imaging requisition and completion, and time to final patient disposition. ⋯ Presence of an ED CT scanner is associated with decreases in time to CT scan completion, radiologic interpretation, and patient disposition.

The aim of this study was to assess the effect of applying ACR Lung-RADS in a clinical CT lung screening program on the frequency of positive and false-negative findings. ⋯ The application of ACR Lung-RADS increased the positive predictive value in our CT lung screening cohort by a factor of 2.5, to 17.3%, without increasing the number of examinations with false-negative results.

The aim of this study was to explore how women respond to the wording of dense breast tissue notifications, which are increasingly required by state law after mammography. The specific aims were to (1) determine whether perceived lifetime risk for breast cancer and intentions to undergo mammography increase after reviewing a sample notification, (2) explore individual difference variables (eg, minority status, insurance coverage) that may influence intentions for additional ultrasound screening, and (3) assess whether anxiety mediates the relationship between perceived risk and screening intentions. ⋯ Women who receive dense breast tissue notifications may generally increase their breast cancer screening intentions; however, intention strength varies depending on internal (eg, ambiguity aversion) and external (eg, insurance for ultrasound) factors. Although perceived risk increases after notification, it is anxiety that drives women's intentions for future screening.
