摘要
目的探讨多b值DWI在前列腺癌M R诊断中的应用效果。方法选取经我院超声引导下前列腺穿刺活检病例证实的30例患者为研究对象,分为前列腺癌组和非癌组,每组15例患者,采取1.5 T MR扫描仪对多b值DWI序列进行扫描,根据b值组合分为组A、组B、组C分别为(0,200,400,600s/m m2),(0,4 0 0,6 0 0,8 0 0 s/m m2),(0,400,600,800,1000s/mm2),比较癌区与非癌区纯扩散值D、灌注分数f的差异。结果组A、组B、组C癌区与非癌区D值分别为(0.94±0.12)×10-3m m2/s和(2.0 4±0.1 9)×1 0-3m m2/s,(0.7 6±0.0 7)×1 0-3m m2/s和(1.8 3±0.1 8)×1 0-3m m2/s;(0.7 8±0.0 4)×1 0-3m m2/s和(1.81±0.23)×10-3mm2/s。组A、组B、组C癌区与非癌区f值分别为(26.1±7.1)%和(9.1±2.8)%;(1 5.2±2.6)%和(3.6±1.4)%;(1 5.9±5.1)%和(3.3±0.6)%。在组A、组B、组C中,癌区与非癌区的D值与f值比较差异均具有统计学意义(P<0.05)。结论在前列腺MR诊断中,b值优化组合能够有效提取前列腺扩散和灌注信息。
Objective Objective To discuss The effect of Multi-b-value DWI in the MR diagnosis of prostate cancer. Methodsthods 30 cases of Patients of Ultrasound-guided prostate biopsy proven were selected and divided into two groups, prostate cancer group and Non-cancer group, there was 15 cases of Patients in each group. 1.5T MR scanner was used in Multi-b-value DWI sequence scanning, according b value combinations were divided into Group A, Group B, Group C,（0,200,400,600s/mm2）,（0,400,600,800s/mm2）,（0,400,600,800,1000s/mm2）,the differences of Value of pure diffusion, perfusion fraction f were Compared in three groups. Results Results Group A, group B, group C cancer and non-cancer District area D values were（0.94±0.12）×10-3mm2/s and（2.04±0.19）×10-3mm2/s;（0.76±0.07）×10-3mm2/s and（1.83±0.18）×10-3mm2/s;（0.78±0.04）×10-3mm2/s and（1.81±0.23）×10-3mm2/s. Group A,group B, group C cancer and non-cancer area district f values were（26.1±7.1）% and（9.1±2.8）%;（15.2±2.6）% and（3.6±1.4）%;（15.9±5.1）% and（3.3±0.6）%. In group A, group B and group C, the D value and f value difference in the cancer and non-cancer areas were statistical significant（P〈0.05）. Conclusion Conclusion In the MR diagnosis of prostate, b value optimal combination can Effective diffusion and perfusion information extraction prostate.
