Abstract:
Objective To explore the value of transrectal ultrasound (TRUS) combined with imaging techniques in the diagnosis of benign and malignant prostate nodules.Methods Totally 170 suspected prostate carcinoma patients were selected and treated with TRUS before puncture.Taking pathological results as the gold standard,the accuracy,specificity,sensitivity,positive predictive value and negative predictive value of transrectal power Doppler ultrasound (PDI),transrectal realtime tissue elastography (TRTE) and PDI combined with TRTE in diagnosis of benign and malignant prostate nodules were compared.Results In the diagnosis of prostate cancer by PDI,the sensitivity,specificity,positive predictive value,negative predictive value and accuracy were 72.9％,74.3％,78.7％,67.9％ and 73.5％ respectively,while for the TRTE were 73.9％,78.4％,81.6％,69.9％ and 75.9％,and there were no significant differences (P ＞ 0.05).PDI combined with TRTE was able to increase the sensitivity (94.8％),negative predictive value (90.9％) and accuracy (82.9％) for diagnosis of prostate nodules (P ＜0.05).Conclusion Transrectal PDI and TRTE can be used as a single indicator of benign and malignant prostate nodules.The combination of the two methods can gain high sensitivity,negative predictive value aud accuracy.
