MR imaging-guided prostate biopsy with surgical navigation software: device validation and feasibility

Radiology. 2001 Jul;220(1):263-8. doi: 10.1148/radiology.220.1.r01jl44263.

Abstract

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.
