To evaluate the value of diffusion-weighted MRI (DWI) in the diagnosis of acute appendicitis. ⋯ DWI is a valuable technique for the diagnosis of acute appendicitis with both qualitative and quantitative evaluation. DWI increases the conspicuity of the inflamed appendix. We recommend using DWI to diagnose acute appendicitis.

To identify CT findings that predict mortality in acute respiratory distress syndrome (ARDS) and to identify CT findings that differentiate diffuse alveolar damage (DAD) from DAD with prominent histopathological features of organizing pneumonia (DAD-OP). ⋯ Our study suggests that >80% of lung involvement, RA/LA ratio >1, and varicoid bronchiectasis predict mortality in patients with ARDS/DAD. Signs of right-sided heart failure (PA dilation greater than 3 cm and RV/LV ratio greater than 0.9) approached significance. CT findings did not differentiate DAD from DAD-OP.

To compare the diagnostic performance of full-field digital mammography (FFDM) with screen-film mammography (SFM) in a corporate screening programme including younger women. ⋯ Cancer detection rates were significantly higher for FFDM than for SFM, especially for women <50, and cancers detected as clustering microcalcifications.
