| 摘 要： | 目的评价前列腺癌内分泌治疗后磁共振的表现.方法分析20例前列腺癌患者内分泌治疗前后磁共振的图像,观察内分泌治疗后前列腺及肿瘤体积、信号的变化和动态增强扫描后肿瘤强化信号的变化.结果快速动态增强扫描后的时间-信号强度曲线显示,注药后肿瘤增强强度从治疗前平均信号强度141.6±12.3MRU下降至治疗后平均信号强度117.2±12.8MRU(t=3.79.P＜0.01)用直线回归分析本组病例内分泌治疗后肿瘤增强信号强度的下降与相应的血清PSA水平下降之间呈显著正相关性(r=0.76.P＜0.01).结论前列腺癌内分泌治疗后磁共振的表现为前列腺及其肿瘤体积缩小、信号减低;肿瘤血流灌注量减少;精囊的体积缩小、信号减低;肿瘤浸润包膜的程度减轻等变化.
