Comparative Study
[The role of whole body spiral CT in the primary work-up of polytrauma patients--comparison with conventional radiography and abdominal sonography].
To evaluate the role of routine "whole body spiral CT"in the primary work-up of polytrauma patients for injuries of the thorax, abdomen and spine, and to compare the results with those of conventional radiography of the chest and spine and abdominal ultrasound. ⋯ Routine performance of whole body spiral CT as part of the primary work-up of polytrauma patients provides a fast and comprehensive survey and detects almost all soft tissue injuries of the chest and abdomen. It is clearly superior to chest radiography and abdominal sonography. All spinal injuries relevant for the acute management were also seen on CT, but not on conventional radiography.

The implantation of permanent (> 14 days) central venous catheters is constantly increasing, accelerated by a trend toward outpatient therapies. Subcutaneous tunneled and non-tunneled catheters as well as port systems are available. The interventional radiologist plays an important role in the implantation of central venous catheters as well as in detection and treatment of any complications. ⋯ The use of peel-away sheaths allows the radiologist to implant subcutaneous tunneled catheters via the Seldinger technique without surgical preparation. Procedure-related early and late complications may occur, and the radiologist plays an important role in the surveillance and management of catheter-associated complications. This review demonstrates the different catheter systems and implantation techniques.

Comparative Study
[Diagnostic imaging in polytrauma: comparison of radiation exposure from whole-body MSCT and conventional radiography with organ-specific CT].
To compare the radiation dose of whole-body multislice CT (MSCT) and conventional radiography with organ-specific CT in polytrauma. ⋯ Whole-body MSCT in polytrauma compared to conventional radiography with organ-specific CT induces a threefold increased dose in unfavorable situations and no increased dose in favorable situations. Nevertheless, routine use of whole-body MSCT should be critically evaluated and should be adapted to the clinical benefit.

Evaluation of vertebroplasty using a combination of CT-fluoroscopy and conventional lateral fluoroscopy in patients with osteoporotic vertebral fractures. ⋯ Percutaneous vertebroplasty is effective for stabilization and pain management of osteoporotic vertebral fractures. The procedure can be safely performed in conscious sedation and local anesthesia. Compared to conventional fluoroscopy alone, CT fluoroscopy provides an excellent additional monitoring of the procedure and probably contributes to the safety of the procedure.
