MR Imaging‒Guided Intervention: Evaluation of MR Conditional Biopsy and Ablation Needle Tip Artifacts at 3T Using a Balanced Fast Field Echo Sequence

Purpose To systematically investigate artifacts produced by biopsy and ablation needles imaged at various trajectories with respect to the static magnetic field (B0). Materials and Methods An acrylic phantom was scanned using a rapid balanced fast field echo sequence with 3.0-T magnetic resonance imaging. A 15-gauge microwave needle, a 17-gauge cryoneedle, and an 18-gauge coaxial biopsy needle were imaged in sagittal and axial planes, in 7...
