Comparative StudyClinical comparison of two optional vena cava filters.
To compare the clinical safety and efficiency of two optional inferior vena cava (IVC) filters. ⋯ Both optional IVC filters are safe and seem to prevent symptomatic PE. On the basis of the fluoroscopy times, the OptEase filters appear to be more operator-friendly. Late filter-associated complications are rare with these filter designs.

Interventional radiology simulation: prepare for a virtual revolution in training.
It is becoming increasingly difficult to learn interventional radiology (IR) skills because there are fewer "straightforward" invasive diagnostic imaging studies, a reduction in the time available for training, concerns about patient safety, and changing patient perceptions. Computer-based simulation has the potential to allow an operator to realistically perform a virtual procedure with feedback about performance and could remove at least some of the patient's role during the learning curve. To do this effectively requires a strategy for integrating simulator models into curricula and the development of standards for their validation.

Analysis of tip malposition and correction in peripherally inserted central catheters placed at bedside by a dedicated nursing team.
To analyze the patterns of postplacement tip malposition in peripherally inserted central catheters (PICCs) placed at bedside, and to describe results of bedside and imaging-guided correction of tip malposition. ⋯ Tip malposition is relatively frequent with bedside placement of PICCs. Preliminary data suggest that most malpositions can be corrected with bedside techniques. Spontaneous correction may occur but is relatively uncommon.

Analysis of simulated angiographic procedures. Part 2: extracting efficiency data from audio and video recordings.
To create and test methods of extracting efficiency data from recordings of simulated renal stent procedures. ⋯ Task analysis facilitated both protocol development and data analysis. Efficiency metrics were readily extracted from recordings of simulated procedures. Aggregating the metrics and dividing the procedure into segments revealed potential insights that could be easily overlooked because the simulator currently does not attempt to aggregate the metrics and only provides data derived from the entire procedure. The data indicate that analysis of simulated angiographic procedures will be a powerful method of assessing performance in interventional radiology.
