MR-Guided Biopsy of the BoneT), a combination of an integrated X-ray fluoroscopy C-arm and CT and, more recently, magnetic resonance imaging (MRI) has enabled us to obtain cytologic or histologic specimens from sites previously thought to be inaccessible using a percutaneous approach.

Field Inhomogeneity-Based Catheter Visualizationd and catheter is very low compared to conventional X-ray fluoroscopy. An additional disadvantage is that MRI has lower spatial and temporal resolution. In this chapter, a new method for visualizing catheters via MRI using locally induced, interactively adaptable field inhomogeneities is presented.

Fast Imaging Techniques for MR-Guided Biopsiest al. 1995), the inherent susceptibility artifact of MR-compatible needles can be used for depiction and localization of the needle itself. Furthermore, doping with paramagnetic substances may prove effective not only for catheters, but also for needles (see Chap. 6).
