Objective To investigate the clinical value of cognitive fusion of ultrasound and MRI in ultrasound-guided transperineal biopsy of prostate cancer(PCa).Methods A total of 30 patients with suspected prostate cancer and prostate specific antigen(PSA)greater than 10 ng/mL were selected from January 2019 to December 2021 in the second affiliated Hospital of Qiqihar Medical University.Ultrasound and MRI cognitive fusion targeting system puncture and single system puncture were used.The overall detection rate of prostate cancer and the detection rate of clinically significant prostate cancer(csPCa)by different methods were compared and analyzed.Results Among the 30 patients,28 cases were positive by pathology;of which 25 cases were positive,5 cases were negative,1 case was misdiagnosed and 4 cases were Missed diagnosis by ultrasound and MRI cognitive fusion targeting system;21 cases were positive,9 cases were negative,1 case was misdiagnosed and 8 cases were missed by single system puncture.The positive accuracy and sensitivity of ultrasound and MRI cognitive fusion targeting combined puncture method were higher than those of single system puncture method,but the missed diagnosis rate was lower than that of single system puncture method,and there was significant difference between the two different puncture methods in the detection rate of PCa.There was significant difference in the detection rate of csPCa between the two puncture methods(χ2=13.631),and the positive rate of single needle in the combination of ultrasound and MRI cognitive fusion system was higher than that in the single system,but there was no significant difference in Gleason score between the two methods(P>0.05).Conclusion The diagnostic value of ultrasound and MRI cognitive fusion system puncture biopsy is better than that of single system puncture in the diagnosis of prostate cancer,and can effectively improve the detection rate of prostate cancer.
