更新更新下叭。 核磁共振有三种成像方式T1WI(T1 Weighted Image)、T2WI(T2 Weighted Image)和PDWI(Proton Density Weighted Image) 那么这一篇就写写这三种成像方式。 为什么需要不同的成像方式呢?因为不同的病灶有不同的特点。我们需要根据其特点成出一个更有利于诊断的图像。 比方下面两张图像。就是对同一个部位...
百度试题 题目T2加权像(T2 Weighted image) 相关知识点: 试题来源: 解析 用长TE时,组织间信号强度差别主要依靠T2,这种由T2差别形成的图像称T2W。反馈 收藏
T2IW:T2 weighted image,T2加权像以横向驰豫(自旋-自旋弛豫)时间T2为权重的磁共振图像。(信号强度主要由T2决定的MR图像即为T2WI。)
1) T2-weighted image T2加权像1. Objective To explore the low field strength MRI of T1,T2-weighted images (T1,T2WI) signal for the diagnosis of intracerebral hemorrhage. 目的:探讨安科低场强MRI的T1、T2加权像(T1、T2WI)的信号对于脑内出血的诊断价值。

T1加权像(T1 Weighted image) 答案:用短TR时,组织间T1强度差别显示出来,这种由T1差别形成的图像称T1加权图像。 手机看题 填空题 肿瘤边缘征象包括:()等。 答案:分叶征、短毛刺征、胸膜凹陷征 手机看题 名词解释 双期扫描 答案:利用螺旋CT扫描速度快,可以控制扫描期相的优势进行动脉期、门脉期的扫描技术,以提...
MRI图像若主要反映的是组织间T1值差别,为T1加权像(T1 weighted image,T1WI);如主要反映的是组织间T2值差别,为T2加权像(T2 weighted image,T2WI);如主要反映的是组织问质子密度弛豫时间差别,为质子密度加权像(proton density weighted image,PdWI)。人体不同组织及其病变具有不同的T1、T2值和质子密度弛豫时间,因此...
