Comparative Study
[Is the Canadian CT head rule for minor head injury applicable for patients in Germany?].
To evaluate the applicability of the Canadian CT Head Rule (CCHR) on head trauma patients in a German university hospital. ⋯ The Canadian CT Head Rule for patients with minor head trauma is applicable with a very high sensitivity and the potential of significantly reducing the rate of cranial CT examinations in these patients.

Comparative Study
[Diagnostic evaluation of chronic inflammatory intestinal diseases in children and adolescents: MRI with true-FISP as new gold standard?].
To evaluate the impact of magnetic resonance imaging (MRI) with use of True-FISP sequences in the evaluation of inflammatory bowel-wall changes in children and adolescents with Crohn's disease. Furthermore, the diagnostic procedure in children and adolescents with chronic inflammatory bowel disease (IBD) will be discussed in light of the relevant literature. ⋯ The described small bowel MRI examination is appropriate for children and adolescents. With the use of True-FISP sequences, it is a convincing method with an outstanding sensitivity in the diagnosis of IBD. Not least because of the lack of radiation exposure, small bowel MRI ought to replace conventional enteroclysis as a gold standard for IBD diagnosis in children and adolescents.

Comparative Study
[Computed tomographic criteria as expected effect to inhaled nitric oxide in patients with severe acute respiratory distress syndrome].
Inhaled nitric oxide (iNO) is an effective therapy for severe hypoxemia in most patients with acute respiratory distress syndrome (ARDS). For unknown reason, a subset of ARDS patients does not respond favorably to iNO therapy. We hypothesized that radiological manifestation of lung injury may be related to iNO response. ⋯ Our data demonstrate that the gross morphological distribution of pathological lung tissue influences iNO response in ARDS. Inhaled NO was most beneficial in injured lungs characterized by many small consolidated areas surrounded by normal lung tissue. The increased borderline between pathologic and normal lung tissue offers additional possibility for iNO to divert blood flow from shunt areas to ventilated lung regions, which consequently improves arterial oxygenation.
