Abstract

Abstract: Objective To study the clinical value of multiparameter magnetic resonance imaging (mpMRI) and ultrasound fusion navigation technology in targeted prostate puncture. Methods Totally 40 patients with suspected prostate cancer who were diagnosed by mpMRI were selected as the subjects. mpMRI and ultrasound fusion technology were applied in targeted prostate biopsy, and the pathological results were observed and analyzed. Results A total of 27 patients were diagnosed by targeted puncture and prostate system puncture, with the positive rate 67.50%. Among 27 diagnosed cases, 21 patients were diagnosed by targeted puncture (52.50%) and 18 by systematic puncture (45.00%), without significant difference between the two groups (P=0.607). The positive rate of single needle for systematic puncture was 14.41% (69/479) and that of single needle for targeted puncture was 47.57% (49/103), with significant difference (P<0.05). Conclusion The MRI and ultrasound fusion technology in targeted prostate puncture show high value. It can detect high-risk prostate cancer with fewer puncture needles. Combination with systematic puncture can improve the positive detection rate of prostate puncture biopsy and reduce the missed diagnosis of prostate cancer patients with high Gleason score. Targeted puncture with prostate imaging reporting and data system (PI-RADS) scoring system can improve the detection rate of clinically significant prostate cancer and help to reduce the number of missed high-risk prostate cancer patients.
