Aims and objectives

The multiparametric magnetic resonance imaging (MRI) is a non-invasive imaging modality, which has revolutionized the ability to diagnose prostate cancer. Prostate Imaging-Reporting and Data System (PI-RADS) version 2 is widely used by many radiologists in practice. It enables data collection and outcome monitoring, reduces variability in imaging interpretations and improves the interdisciplinary communications with referring clinicians. In-bore magnetic resonance-guided biopsy has been increasingly used in clinical practice to detect clinically significant prostate cancer.The aim of this study is to assess the effectiveness and accuracy of...

Methods and materials

23 patients (aged 45-69), with rising PSA level and PI-RADS 4 peripheral lesions underwent MR-guided In-Bore prostate biopsy. The multiparametric magnetic resonance imaging (MRI exam was performed with high-field 3T and 1,5T scanners. The changes were assessed in accordance with the Prostate Imaging-Reporting and Data System (PI-RADS) Version 2. Magnetic resonance imaging (MRI) guided biopsy was performed with MRI-compatible biopsy Set, with150mm/16g needle gun. The navigation of the needle was done with T2 WI in the coronal and sagittal plane.

Results

Based on the histological results after the magnetic resonance imaging (MRI) - guided biopsy 9 patients were diagnosed with adenocarcinoma (Gleason score 4+3=7), 5 patients were diagnosed with adenocarcinoma (Gleason score 3+4=7), 5 patients were diagnosed with adenocarcinoma (Gleason score 3+3=6), and in 4 patients prostate cancer was not detected.

Conclusion

Magnetic resonance imaging (MRI) - guided in-bore prostate biopsy is an efficient and accurate procedure for prostate cancer detection in patients with PI-RADS 4 peripheral lesions.
