Seven-step protocol for prostate biopsies performed under TRUS guidance with mp-MRI targeting.
|MRI room|| Radiologist||1||Target detection||Detection of mp-MRI lesions having a cancer suspicion score ≥3 and a significant size. A mean of two targets is a good compromise, with a primary target clearly identified. |
|2||Target reporting||Transmission of intelligible and accurate information to the physician that will perform the biopsy procedure.|
|TRUS biopsy room||Urologist/radiologist/both||3||Intermodality fusion||Registration (or “fusion”) of static, asynchronous, and multiparametric MRI data with that of a real-time and dynamic TRUS data.|
|4||TRUS guidance to target(s)||Guidance of the biopsy needle gun to the correct location of the mp-MRI target within the TRUS image volume.|
|5||Sampling simulation||Simulation the sampling helps the physician assess the quality of the sampled core, as well as the safety of the sampling.|
|6||Tissue sampling||Tissue sampling is usually performed using a semiautomatic needle biopsy gun triggered by the physician.|
|7||TRUS biopsy report and quality insurance||Reporting of the biopsy procedure, including the location of this additional cores and the correspondence with suspicious mp-MRI image.|
