In vitro assessment of needle artifacts with an interactive three-dimensional MR fluoroscopy system.
To perform in vitro assessment of needle artifacts with an interactive three-dimensional (3D) near-real-time magnetic resonance (MR) fluoroscopy system for musculoskeletal interventions in a 1.5-T open-bore magnet. ⋯ Because of its robustness in depicting needle artifacts, the interactive 3D MR fluoroscopy system appears to be suitable for MR-guided interventions. The titanium needle showed optimal artifacts with all combinations of measurement parameters. Artifacts with the other needles were too large (Inconel) or too small (carbon fiber).

Case ReportsThe use of the internal thoracic vein for percutaneous central venous access in an infant.
Central venous access can be challenging in children with thrombosed central veins, particularly those who are dependent on parenteral nutrition. The present report describes a 2-year-old child with short bowel syndrome and chronically thrombosed jugular, subclavian, and femoral veins in whom a tunneled central venous catheter was successfully placed percutaneously via the internal thoracic vein.
