Background: We evaluated the ability of 3D-CT and virtual bronchoscopy to estimate trachea stenosis in comparison to conventional axial CT and fiberoptic bronchoscopy, with a view to assist thoracic surgeons in depicting the anatomical characteristics of tracheal strictures.

Even though the therapeutic outcome for the three groups was similar, the degree of clinical response and reossification differed.

Our results show a clear correlation between the type of bone metastases and the clinical status of patients. Patients with excessive bone resorption suffer the most, and may be given priority in treatment. CT proved to be a practical and efficient method to investigate and classify metastatic bone lesions.

This study demonstrates that oval cells develop and proliferate in a model of experimental liver fibrosis without pretreatment with a known hepatocytic inhibitor. However, further research is warranted in order to identify the exact molecular mechanisms involved in this process.
