[Abstract]:Objective: to evaluate the value of quantitative analysis of ADC value in the diagnosis and differential diagnosis of prostate cancer, to explore the correlation between ADC value and Gleason score of prostate cancer, and to evaluate the value of ADC value in the grading of prostate cancer. The value of choice of treatment regimen and prognosis evaluation. Materials and methods: 89 cases of prostate cancer confirmed by ultrasound guided biopsy or surgery and pathology from 2010 to 2013 in the affiliated Hospital of Qingdao University were retrospectively analyzed. The prostate lesions were divided into prostate cancer group according to the pathology. The ADC value of ROI and Gleason score of prostate cancer were recorded in benign prostatic hyperplasia group and normal tissue group. The difference of ADC in prostate cancer, prostatic hyperplasia and normal prostate tissue was analyzed by comparing the pathological results. The ROC curve of ADC value in diagnosis of prostate cancer was also analyzed. To analyze the correlation between ADC value and Gleason score of prostate cancer, and the difference of ADC value among each score group, and to analyze the ROC curve of prostate cancer in high risk group of ADC value diagnosis at the same time. Results there were 543 effective ROI, 224 ROI, 276 ROI in benign prostatic hyperplasia and 43 ROI in normal prostate tissues in 89 cases of benign prostatic diseases. There was significant difference in ADC value between prostate cancer focus and noncancerous lesion corresponding to ROI. There was significant difference in ADC value between prostate cancer group, prostate hyperplasia group and normal tissue group, there was significant difference between prostate cancer group, prostate hyperplasia group and normal tissue group, and there was significant difference between prostate cancer group and prostate hyperplasia group (P 0.01), and there was no significant difference between prostate cancer group and prostate hyperplasia group. There was significant difference in ADC value between normal group (P 0.05) and normal tissue (P 0.05). According to ROC curve analysis, the diagnostic specificity and sensitivity of prostate cancer were higher when truncation value was less than 1.08 脳 10~(-3)mm~2/s. 84.8% and 95.9%, respectively, which can obtain higher diagnostic efficiency. There was a negative correlation between ADC value and Gleason score in prostate cancer, there was significant difference in ADC value between Gleason score group and ADC score group. There was significant difference in ADC value between multiple comparison Gleason score group and 7 group and 8 score group with 9 group. There was significant difference in ADC value between Gleason score group and Gleason score group (P < 0.01), and there was significant difference in ADC value between Gleason score group (P < 0.05) and Gleason score group (P < 0.05). There was a significant difference in ADC value between Gleason score group and Gleason score group (P < 0.05). There was no significant difference in ADC values among the groups with scores of 7, 8 and 9. When the truncation value of ROC curve was less than 0.997 脳 10~(-3)mm~2/s, there was no statistical difference between the two groups (P < 0.05). The specificity and sensitivity of Gleason score 鈮,
