MRI-TRUS Fusion Biopsy Accurate. (cover story)The article reports on a study by Eduard Baco of Oslo University Hospital Aker in Oslo, Norway, and colleagues, suggesting that the use of magnetic resonance imaging-tansrectal ultrasound (MRI-TRUS) fusion can reliably predict the location and ...

Detection of significant prostate cancer using target saturation in transperineal magnetic resonance imaging/transrectal ultrasonography-fusion biopsy[J]. Eur Urol Focus, 2021, 7(6): 1300-1307. DOI: 10.1016/j.euf.2020.06.02...
TRUS/MRI Fusion guided biopsy protocol: Step 1:The appropriate MRI sequence (Figure 2) was selected and the dataset imported onto the Resona 9 and into the live ultrasound exam. Figure 2. The hypo-signal lesion in the right anterior lobe of the prostate was displayed most clearly on the...
MRI与经直肠超声(transrectal ultrasound,TRUS)融合前列腺靶向活检(targeted prostate biopsy,TB)应运而出。认知融合靶向活检(cognitive fusion targeted biopsy, COG-TB)是其中重要的部分,已有多个研究从各方面分析其优劣性[ 2 , 3 , 4 ]。然而,对于单个感兴趣区域(regions of interest,ROI),TB的最佳活检针数尚未...
We retrospectively analyzed the clinical and pathological data of 81 patients with mpMRI-TRUS image fusion targeted transperineal prostate biopsy using electromagnetic needle tracking under local anesthesia. Visual analog scale (VAS) and visual numeric scale (VNS) were used to evaluate the pain level ...

Conclusion:PI-QUAL has only a limited impact on PI-RADS diagnostic performance in patients scheduled for MRI-TRUS fusion biopsy. However, the lower cancer prevalence in the lower PI-QUAL categories points out a risk of false-positive referrals and unnecessary biopsies if prostate imaging quality ...
METHODS: Retrospective single-centre outcome of transperineal MR/TRUS fusion-guided biopsies of 221 men with MRI lesions, prospectively collected between 2016 and 2018. All men underwent transperineal targeted biopsy (TB) with 2-4 cores, followed by a median of 24 systematic biopsies (SB). Cancer...
The information gained from both imaging and biopsy allows thebest treatment decision. Is MRI/ultrasound fusion guidance the same as real time in-bore MRI guidance? No. It is a “co-registration” of two different imaging technologies: MRI and ultrasound. Previously captured MRI images are “fus...
