Comparative Study
Quality evaluation of radiographic contrast media in large-volume prefilled syringes and vials.
The authors compared the particle contaminations of radiographic contrast media packaged in large-volume prefilled syringes and vials. ⋯ The particle counts for contrast media packaged in syringes and vials varied considerably among the different contrast media and were related to the amount of silicone oil on the inner surface and rubber piston of the syringe.

Comparative Study
Computerized delineation and analysis of costophrenic angles in digital chest radiographs.
The authors developed a computerized method for delineating the costophrenic angles in digital posteroanterior chest radiographs to derive quantitative information that allows for detection of abnormal blunting of the costophrenic angle. ⋯ This delineation method enhances the automated lung-segmentation scheme. Quantitative information obtained from the costophrenic angles can be used for automatic evaluation of the presence of costophrenic angle blunting, which may indicate the presence of pleural effusion.
