1. Although interventional MR-guided procedures have conventionally been performed on low- and mid-field open MR systems, performance of interventional MRI at 3 Tesla (T) is technically feasible. 2. Similar to diagnostic imaging, utilization of 3 T MR for procedural guidance presents many potential advantages including the ability to leverage signal-to-noise gains in order to achieve greater temporospatial resolution. 3. Challenges for 3 T interventional MRI include needle artifact reduction, patient access, specific absorption rate, fat saturation and coil limitations.  

Transition to 3T MR Intervention -Standard protocols for effective imaging guidance -Work flow considerations -Overview of advantages and disadvantages versus 1.5 T Pulse Sequence Optimization -Managing specific absorption rate limitations (Level 0 vs. First Level) -Needle artifact reduction techniques (WARP and SEMAC) -Fat saturation approaches (STIR vs. SPAIR vs. spectral techniques) System Attributes and Design -Coil design, optimization, and preparation -In-room console interface -Acoustic noise -Patient access and target localization -Future directions including augmented reality navigation
