The introduced new developed navigation system is a High Intensity Approach Light System for augmented reality in image-guided surgery. The surgeon follows the projected approach lights with his ordinary surgical instruments. Thus, tracked instruments are not necessary with this system.

A prospective case control study design was conducted. ⋯ While performing percutaneous vertebroplasty, the surgeon is exposed to a significant amount of radiation. Proper surgical technique and shielding devices to decrease potentially high morbidity are mandatory. Training in radiation protection should be an integral part of the education for all surgeons using minimally invasive radiologic-guided interventional techniques.

The role of anesthesia outside the operating room is rapidly expanding and evolving alongside with the advances in interventional neuroradiology. Increasingly complex diagnostic and therapeutic neuroradiological procedures are being performed on sicker patients. This review provides an overview of the principles of anesthetic management and summarizes recent advances in interventional neuroradiology. ⋯ Providing anesthesia in the interventional neuroradiology suite continues to be a challenge to the anesthesiologist. Understanding the anesthetic constraints and complexities and keeping abreast of the current developments in neuroradiology are crucial in ensuring the maximal benefits to and safety of patients.

[Radiofrequency ablation of renal cell carcinomas using MR imaging: initial results].
First results of a study about the efficacy of magnetic resonance-(MR-)guided radiofrequency ablation of renal cell carcinomas (RCC) are presented. ⋯ MR-guided RF ablation in an open interventional 0.2T MR-unit is a safe and effective modality for the treatment of RCC. Fast MR-imaging is a convenient method for exact positioning of MR-compatible RF-electrodes. Near on-line MR-monitoring of ablation procedure with T2-weighted imaging allows for immediate assessment of the coagulation extent.

Utility of computerized isocentric fluoroscopy for minimally invasive spinal surgical techniques.
The purpose of this study was to prospectively evaluate the clinical utility and accuracy of intraoperative three-dimensional fluoroscopy as an adjunct for the placement of a complex spinal instrumentation. ⋯ Use of intraoperative three-dimensional fluoroscopy for image guidance in minimally invasive complex spinal instrumentation procedures is feasible and safe. This technique provides excellent visualization of three-dimensional relationships. This potentially results in improved accuracy of screw positioning and the ability to detect misplaced screws prior to wound closure. This technique also potentially results in a significant reduction in radiation exposure for both the patient and the staff.
