Purpose of Technology

Magnetic resonance imaging and transrectal ultrasound (MRI-TRUS) fusion-guided biopsy uses software to combine detailed images obtained from an MRI with the less detailed real-time TRUS, through an overlaid 3-dimensional view. These “fused” images guide the placement of the biopsy needle to suspicious lesions identified from the MRI for prostate biopsy.

Relevant Questions

  • Does MRI-TRUS fusion-guided biopsy provide accurate diagnostic information for patients suspected of having prostate cancer?

  • Does information obtained from MRI-TRUS fusion-guided biopsy improve patient management or outcomes?

  • Is MRI-TRUS fusion-guided biopsy safe?

  • Have definitive patient selection criteria been established for MRI-TRUS fusion-guided biopsy?
