Prostate cancer. Systematic review. Abstract. Context: The introduction of magnetic resonance imaging-guided biopsies (MRI-GB) has changed the paradigm concerning (TRUS-GB) in patients at risk for PCa, and which technique of MRI-GB has the highest image fusion (where the MRI prostate contour is projected.
16 Sep 2014 Prebiopsy multiparametric prostate MRI (mp-MRI), followed by transrectal ultrasound-guided (TRUS-G) target biopsies (TB) of the prostate is a key We discuss the diagnostic yield of visually-registered TB in comparison with conventional biopsy, and TB performed using other registration methods.
The segmentation is initiated with clicking at the approximate center of the prostate in the approximately middlemost slice. We then integrate this information with a priori knowledge of prostate shape in several steps to arrive at the final contour. Then the contour of the middlemost slice is used as

The simplest way of integrating MRI information into TRUS-guided biopsies is cognitive fusion. Modern ablative procedures (eg, high-intensity focused ultrasound therapy, cryotherapy) now allow treatment of very small areas in the prostate. The prostate contour is shown in red and the MRI-suspicious lesion in blue.
CONCLUSION: This algorithm can be used to increase the needle targeting accuracy by alerting the clinician if the biopsy target has moved significantly prior to needle insertion. The proposed method demonstrated feasibility of intra-operative target localization and motion compensation for MRI-guided prostate biopsy.
During the procedure, a special biopsy needle is inserted into the prostate gland through the wall of the rectum to remove several small samples of tissue for pathologic analysis. This method is known as transrectal ultrasound (TRUS) guided biopsy. if transrectal ultrasound is not feasible due to prior rectal surgery.
During the prostate biopsy procedure, the patient was placed inside the MRI scanner in prone position to acquire a series of 2D high resolution T2 weighted axial volumetric slices of the prostate. From the pre-needle insertion volume, the clinicians selected the biopsy location(s) in RAS (Right,
Our work is the first to focus on quantifying the relationship between segmentation error and targeting accuracy in the MRI-guided prostate biopsy procedure. 3. METHODS. The main workflow of the simulator, shown in Fig. 1, begins with the generation of the ground truth pre-op prostate contour instantiated from a statistical
