垂体动态增强病例 垂体瘤强化表现 垂体微腺瘤 垂体T1动态增强系列图像，正常垂体实质呈快速明显强化，垂体微腺瘤在早期无强化，与正常垂体信号差异最明显。 垂体增强病例 垂体微腺瘤强化表现 高分辨率的增强T1图像对显示无强化的微腺瘤非常重要，矢状面图像上可见明显强化的垂体后缘呈低信号的垂体瘤。 垂体增强病例 垂体瘤平扫与增强 高分辨率的T1图像上可见低信号类圆形病灶，比正常垂体信号稍低。增强后T1图像，正常垂体明显强化，而垂体瘤强化相对弱一些。 致谢： 我们感谢下列医院为此扫描方案作出的奉献，并不仅局限于这些医院，我们将陆续添加名单： AN HUI YIJISHAN HOSPITAL SHANGHAI RUIJIN HOSPITAL SHANGHAI YANGSI HOSPITAL SHANGHAI RENJI HOSPITAL ZHENGZHOU MU NO.1 HOSPITAL HEBEI PEOPLE HOSPITAL ZHEJIANG LISHUI HOSPITAL WENZHOU MU NO.1 HOSPITAL SHANXI PINGLU HOSPITAL LIAONING WAFANGDIAN HOSPITAL QIQIHARER NO.1 HOSPITAL SHANDONG QILU HOSPITAL NANCHANG NO.2 HOSPITAL ZHEJIANG MU NO.2 HOSPITAL WUHAN TONGJI HOSPITAL XJ KELAMAYI HOSPITAL HUBEI TONGJI HOSPITAL HUBEI WUHAN MEDICAL CENTER QINGHAI PEOPLE HOSPITAL SHANGHAI NO.1 HOSPITAL SHENYANG MU NO.1 HOSPITAL HUNAN XIANGYA HOSPITAL NINGXIA HOSPITAL SHANXI YUANPING HOSPITAL SHAANXI NO.4 HOSPITAL 磁共振规范化扫描方案（HDe） ---中华磁共振应用学院系列教材 In order to accurately capture a subtle 0.5-3% signal intensity increase… caused by the intensified blood supply to the exercised region of eloquent cortex Need a system with very low intrinsic system variations and noise… to reliably measure subtle physiologic responses Need short exam time … as patient immobility and cooperation in following the tasks are crucial and more of a challenge during lengthy exams Need integrated workflow and interface… with synchronized paradigm management and image acquisition as well as post-processing and analysis tools needed In order to accurately capture a subtle 0.5-3% signal intensity increase… caused by the intensified blood supply to the exercised region of eloquent cortex Need a system with very low intrinsic system variations and noise… to reliably measure subtle physiologic responses Need short exam time … as patient immobility and cooperation in following the tasks are crucial and more of a challenge during lengthy exams Need integrated workflow and interface… with synchronized paradigm management and image acquisition as well as post-
