中文摘要:
      目的 探究在对前列腺癌的诊断中不同 b 值 DWI 技术的诊断价值。 方法 选取我院 2017 年 1 月~ 2018年 1 月收治的 36 例前列腺疾病患者作为本次研究对象,其中前列腺癌患者 20 例,前列腺炎患者 16 例,所有患者均行 DWI 技术扫描,DWI 扫描采用横轴位平面回波成像序列,弥散敏感系数(b)值选取 1000、2000、3000s/mm2,分别分为 A 组、B 组、C 组,探究不同 b 值 DWI 技术在对前列腺癌的诊断中的诊断价值。 结果随 b 值升高,正确诊断前列腺癌和前列腺炎的例数增加,前列腺癌病变在较高的 b 值信号较高,显示更清晰;前列腺炎病变在较高的 b 值上信号不高,显示不清。不同 b 值对于前列腺炎症中前列腺癌和前列腺炎的定性诊断中比较,B 组和 C 组对前列腺癌的诊断明显高于 A 组诊断,B 组、C 组对前列腺癌的诊断的敏感度、特异度及准确度均明显高于 A 组,差异有统计学意义(P < 0.05)。 结论 DWI 检测中高 b 值对诊断前列腺癌有良好的价值,诊断的敏感性和特异性更高,得出的图像更为清晰,利于后期治疗方法的选择,临床价值较高。
英文摘要:
      Objective To explore the diagnostic value of different b-value DWI techniques in the diagnosis of prostate cancer. Methods 36 patients with prostate disease who were admitted to our hospital from January 2017 to January 2018 were selected as research objects,including 20 patients with prostate cancer and 16 patients with prostatitis.All patients underwent DWI technical scanning.DWI scanning adopted the horizontal axis plane echo imaging sequence and the diffusion sensitivity coefficient (b) values was set as 1000,2000 and 3000s/mm2, which were respectively divided into group A,group b,and group C.The diagnostic value of different b-value DWI techniques in the diagnosis of prostate cancer was explored. Results As the value of b increased,the number of cases of correct diagnosis of prostate cancer and prostatitis increased.Prostate cancer lesions were higher at higher b-values and showed clearer.Prostatitis lesions were not high at higher b values and were unclear.Qualitative diagnosis of different b values for prostate cancer and prostatitis in prostatic inflammation were compared.The diagnosis of prostate cancer in group B and group C was significantly higher than that in group A.The sensitivity,specificity and accuracy of diagnosis for prostate cancer in group B and group C were significantly higher than those in group A.The differences were statistically significant (P < 0.05). Conclusion The high b value in DWI detection has good value for the diagnosis of prostate cancer,and the sensitivity and specificity of diagnosis are higher.The obtained images are clearer,which is conducive to the choice of later treatment methods and has higher clinical value.
