Abstract:
This case illustrates the ability of electromagnetic tracking navigation to localize difficult targets in real time during biopsy or ablation of lesions that are only transiently apparent on arterial phase computed tomography and may be unapparent on sonography. Readily available technology enabling multimodality registration to sonography allows for the use of positron emission tomographic, magnetic resonance imaging, and computed tomographic information during sonographically guided procedures and examinations.
