Transperineal MR-guided stereotactic prostate biopsy utilizing a commercially available anorectal biopsy device.
OBJECTIVE
To evaluate the feasibility of transperineal MR-guided prostate biopsy using a stereotactical targeting system originally designed for anorectal usage.


METHODS
A commercially available DynaTRIM MR targeting system (Invivo corp., Gainesville FL, USA) originally designed only for anorectal application was used on a 70 cm wide-bore, whole-body 3 Tesla MR-system (Ingenia, Philips Healthcare, Best, NL). Transperineal biopsy was performed following mulitparametric MR imaging for targeting of the lesion.


RESULTS
The anorectal device allowed for correct localization and successful MR-guided transperineal biopsy of the targeted lesion.


CONCLUSIONS
MR-guided transperineal biopsy is feasible using a commercially available anorectal stereotactic biopsy device. This may lead to a broader acceptance of this approach for targeted prostate biopsies.
