Efficacy of manual aspiration immediately after complicated pneumothorax in CT-guided lung biopsy.
The goal of this study was to evaluate the efficacy of simple aspiration of air from the pleural space to prevent increased pneumothorax and avoid chest tube placement in cases of pneumothorax after computed tomography (CT)-guided lung biopsy. ⋯ Percutaneous manual aspiration of biopsy-induced pneumothorax performed immediately after biopsy may prevent progressive pneumothorax and eliminate the need for chest tube placement. However, in cases in which the amount of aspirated air is large (such as more than 543 mL in this study), the possibility of required chest tube placement increases.

Navigation with electromagnetic tracking for interventional radiology procedures: a feasibility study.
To assess the feasibility of the use of preprocedural imaging for guide wire, catheter, and needle navigation with electromagnetic tracking in phantom and animal models. ⋯ Previously acquired CT, MR, or PET data can be accurately codisplayed during procedures with reconstructed imaging based on the position and orientation of catheters, guide wires, or needles. Multimodality interventions are feasible by allowing the real-time updated display of previously acquired functional or morphologic imaging during angiography, biopsy, and ablation.
