就叫“T1加权成像”（T1-weighted imaging），临床工作中也经常简称“T1”。
High-resolution T1-weighted images were acquired using spoiled gradient recalled sequence on a 3 T MRI system (Tim Trio; Siemens,Erlangen, Germany) with an eight-channel head coil at West China Hospital. The main ...
The T2-weighted images can be produced as quickly as T1-weighted images by using a small pulse angle and a long TE; it is not necessary to use a long TR to reduce the effects of T1 differences. Optimum pulse angles are calculated, and the potential advantages and disadvantages of T2-...
This article shows a new method of the automatic registration of T1- and T2-weighted MR knee images. This method is based on the entropy and energy measures of fuzziness and can be used in localization process of cruciate ligament. First, two sequences (T1- and T2-weighted) are converted ...
On T1- and T2-weighted magnetic resonance (MR) images obtained at 0.14 T the rat brain was visible in the rat head as an area of relative high signal intensity. The enlarged lateral ventricles produced by intrastriatal injections of the excitotoxin kainic acid (KA) were clearly visible as ...

aAt MR imaging, such necrotic areas are seen as areas of slightly high signal intensity on T1-weighted images and heterogeneous areas on T2-weighted images. 在想象先生,这样坏死的区域在T1被衡量的图象在T2被衡量的图象看,轻微地高信号强度区域和异种区域。 [translate] ...
此外,近年来皮质联络纤维被认为是能更灵敏反映AD病理的破坏效应,而基于T1-/T2-weighted ratio mapping是一种新近提出的,能有效研究这一指标的技术,这一方法可基于现有的T1及T2序列,有效反映灰质皮层内髓鞘含量,较弥散张量成像的方法更为简易,有效.研究方法:本研究的数据来自于公共数据库ADNI.根据AD生物学诊断标准,...
