摘要 目的探讨前列腺癌MRI动态增强扫描定量参数Ktrans值的变化与病理Gleason评分的关系。资料与方法经穿刺活检证实的78例前列腺癌患者行MRI动态增强扫描检查,在Ktrans参数图上画取感兴趣区测量前列腺相应部位的Ktrans值,分析其与穿刺病理结果Gleason评分的相关性。结果前列腺癌区Ktrans值与Gleason评分呈正相关(r=0.351,P<0.05)。结论前列腺癌区Ktrans值与Gleason评分呈正相关;Ktrans值有可能用于评价前列腺癌的分级和预后。 Purpose To investigate the relationship between Ktrans value,the quantitative parameter of dynamic contrast-enhanced MRI（DCE-MRI） of prostate cancer,and Gleason score.Materials and Methods DCE-MRI was performed in 78 cases confirmed of prostate cancer with biopsy.ROI was drawn on the map of Ktrans parameters to measure the prostatic Ktrans value of the corresponding area.The correlation between the Ktrans value and the Gleason score was analyzed.Results The Ktrans value of prostate cancer was positively correlated with Gleason score（r =0.351,P 0.05）.Conclusion The Ktrans value of prostate cancer is positively correlated with Gleason score;Ktrans value may be used to evaluate the classification,the grading and the prognosis of prostate cancer.
