The multiplanar imaging capabilities of MR are of great advantage for real-time needle guidance. The focus of this work is to clinically evaluate an advanced MR guidance approach for percutaneous needle interventions providing an interactive, real-time multi-slice pulse sequence (Beat_IRTTT) in combination with an interventional MRI software package (Interactive Front End, IFE). This approach was used for 9 spinal infiltrations and 6 abdominal biopsies. To our experience, automatic real-time slice alignment greatly simplifies the workflow. The proposed real-time slice layout with three slices along the planned trajectory orthogonal to each other further allows for efficient and safe needle placement.
