Comparative Study
Signal characteristic and enhancement patterns of pancreatic adenocarcinoma: evaluation with dynamic gadolinium enhanced MRI.
To determine the signal characteristics and enhancement patterns of proven pancreatic adenocarcinomas at 1.5 T and to compare these results with contrast enhanced computed tomography (CECT). ⋯ The results of the present study showed that all 25 pancreatic adenocarcinomas were hypointense to pancreatic parenchyma during the arterial phase. Moreover, MRI may be useful in patients with a high suspicion of pancreatic carcinoma that is not visualized during CECT.

Multicenter Study
Analysis of the factors associated with radiofrequency ablation-induced pneumothorax.
To define the characteristics most likely to result in radiofrequency ablation (RFA)-induced pneumothorax. ⋯ The number of tumours, electrode positions, and the anticipated electrode trajectory through aerated lung impacts on the likelihood of a pneumothorax. These considerations should be factored into patient selection, the choice of approach, and trajectory used in RFA.

The aim of this study was to validate the computed tomography (CT) features of intra-abdominal hypertension (IAH) by relating them to the clinical measurement of intra-abdominal pressure (IAP) in critically ill surgical patients. ⋯ The presence of RBS and BWTE on CT images of critically ill surgical patients should alert clinicians to the possibility of presence of IAH and ACS, and prompt measurement of the IAP and consideration of suitable interventions.
