Needle Heating During Interventional Magnetic Resonance Imaging at 1.5- and 3.0-T Field Strengths

Fritz Fig1b Objective: The aim of this study was to test the hypothesis that clinically used magnetic resonance (MR)–conditional needles of varying lengths, orientations, locations, and pulse sequences can result in excessive heating during MR imaging (MRI)–guided interventions that can be minimized to physiological ranges with proper selection of the needle length, needle position, and modification of pulse sequence parameters.  View/Download
