Abstract

Purpose : To analyze the effectiveness of magnetic resonance imaging (MRI)-guided prostate needle biopsies using BioJet navigation.

Methods : We retrospectively reviewed 280 patients who underwent MRI-guided biopsies at our institution. Patients with a prostate specific antigen (PSA) level＞4.0 ng/mL and suspicious prostate cancer (PCa) lesions by multiparametric MRI (mpMRI) underwent 2-core MRI-guided targeted needle (TB) and conventional 12-core systematic biopsies (SB) using BioJet navigation.

Results : The median age of patients was 68 years (range 53-79) and median PSA was 7.0 ng/mL (3.1-45.3). The total number of suspicious cancer lesions by mpMRI was 329. Total and clinically significant PCa cases detected were 172 (61.4％), and 139 (49.6％), respectively. On a core-basis analysis, the detection rate for TB was significantly better than for SB (38.3％ vs. 9.2％, respectively ; p＜0.0001).

Conclusions : MRI-guided targeted needle biopsy using BioJet navigation is effective for diagnostic procedures and estimations of PCa.
