MR Imaging-guided Prostate Biopsy with Surgical Navigation Software: Device Validation and Feasibility

Magnetic resonance (MR) imaging–guided prostate biopsy in a 0.5-T open imager is described, validated in phantom studies, and performed in two patients. The needles are guided by using fast gradient-recalled echo and T2-weighted fast spin-echo images. Surgical navigation software provided T2-weighted images critical to targeting the peripheral zone and the tumor. MR imaging can be used to guide prostate biopsy.
