Abstract:
Objective To evaluation the value of fusion images of dynamic contrast enhanced MRI (DCE MRI) with transrectal ultrasound(TRUS) and conventional TRUS in prostate biopsy for prostate cancer.Methods The clinical data of 127 patients suspected as early-stage prostate cancer were retrospectively analyzed.79 patients underwent prostate biopsy guided by conventional TRUS(group A).48 patients underwent prostate biopsy guided by fusion images of DCE MRI with TRUS(group B).Then the diagnostic rates,puncture times and complications in the two groups were compared.Results The cases with confirmed prostate cancer were 31 in group A and 22 in group B.The first time diagnostic rates of biopsy were 20.2％(16/79) in group A,and 39.3％ (19/48) in group B respectively(P ＜0.05).The first time sensivity,specifity,positive predictive value and negative predictive value of biopsy were 51.6 ％,100 ％,100％,77.4％ in group A and 86.3％,100％,100％,89.6％ in group B.Puncture times was 15.40 ± 4.67 and 13.01 ± 3.87 respectively.The Gleason score was 6.21 ± 0.91 and 6.35 ± 0.81 respectively.The complication rates were 19.0％(15/79) in group A and 12.5％(6/48)in group B.Conclusions For patients with earlystage prostate cancer,the combination of DCE-MRI and TRUS to guide transrectal prostate biopsy was recommended.It showed an increase in the first time diagnostic rate of biopsy while a reduction in the times and complications of prostated biopsy.
