The purpose of this study was to find out whether pneumothorax detection and exclusion is superior in expiratory digital chest radiography. ⋯ • Basal pneumothoraces during inspiration demonstrate a greater width than during expiration. • There is statistically no difference between inspiration/expiration for the diagnosis of pneumothorax. • An image taken during inspiration is recommended to confirm or rule out a pneumothorax.

Comparative Study
Cardiac MRI: T2-Mapping Versus T2-Weighted Dark-Blood TSE Imaging for Myocardial Edema Visualization in Acute Myocardial Infarction.
To assess the diagnostic accuracy of T2 mapping for the detection of myocardial edema in acute myocardial infarction (AMI), and to compare this diagnostic accuracy with that of the current standard for myocardial edema imaging, which is T2w dark-blood TSE imaging. ⋯ T2 mapping allows for the visualization of myocardial edema in AMI with a high sensitivity and specificity, and features better diagnostic accuracy in terms of a higher sensitivity compared to T2w dark-blood TSE imaging.

Comparative Study
Experimental investigation of modern and established carotid stents.
The design and material determine the mechanical properties of stents. In vitro parameters such as radial force, flexibility and wall adaptation of different stents were investigated in order to obtain evidence for clinical use. ⋯ The investigation of carotid stents provides an objective comparison of mechanical properties. Conclusions about the respective optimum uses of stents can be drawn from this. The hybrid stents show a good balance of properties for wide applicability.
