查询词典 Gd

Methods:MRI findings of pancreatic carcinoma in 109 cases were analyzed retrospectively. All the cases were confirmed by operation, pathology and clinical practice. Conventional pancreatic sequences ( FLASH 2d T1WI, FLASH 3d T1WI, Declivate transection FS-T1WI, TSE-T2WI), MR cholangiopancreatography and dynamic contrast of Gd-DTPA sequences were used to find pancreatic lumps, adjacent infiltrated blood vessels and small pancreatic carcinoma.

经手术病理和临床证实的胰腺癌109例，经常规胰腺扫描序列（FLASH 2d和3d T1WI、倾斜横断面FS-T1WI、TSE-T2WI）、MRCP、Gd-DTPA动态增强扫描对胰腺癌、胰胆管扩张、周围血管侵犯及小胰腺癌诊断价值。

Results MRI appearances of acoustic neuromas were:（1）The turmor's growth round the internal auditory canal,the Ⅶ,Ⅷ nerves affected side were thickened than that of opposite side.There was no marked demarcation between the main bodies of the tumors and the affected nerves.The connection between tumors and affected nerves could be showed at contrast enhanced imaging.（2）The tumors were of hypo or isohypo intensity on T1 weighted images and hyper or iso hyper intensity on T2 weighted images.（3）After Gd DTPA administration the tumors were homogeneously or inhomogeneously or circularly enhanced.（4）The margins of the tumors were smooth and well delineated.（5）The affected internal auditory canal usually became shorter in depth and larger in posterior anterior diameter.（6）MRI appearances of micro acoustic neuromas were that the affected Ⅶ,Ⅷ nerves were normal in size or nodularly thickened and the tumor reveaed nodular or point enhancement at contrast enhanced MRI.

结果 听神经瘤的MRI表现主要为：（1）肿瘤以内听道为中心生长，第Ⅶ、Ⅷ神经束较对侧增粗，与肿瘤主体多无明确分界，增强后可见两者相连，颇为特征；（2）肿瘤在T1加权图像上呈低信号、略低信号或低等混合信号，T2加权呈高信号或高等混合信号；（3）注射Gd DTPA后肿瘤呈均匀、不均匀或环状强化；（4）肿瘤边界清晰，边缘光整；（5）绝大多数肿瘤患侧内听道前后径扩大，深径缩短；（6）微小听神经瘤的MRI表现为第Ⅶ、Ⅷ神经束正常或局部结状增粗，造影后呈结节状或点状增强。
