以脑脊液信号为例，可描述成长 T1、长 T2 信号 （或 T2WI 上表现为高信号，T1WI 上表现为低信号）；而脑水肿（T2WI 信号不及脑脊液亮但比皮层亮），可描述成稍长（较长）T1、稍长（ …

这种黑白图像指的是黑白信号，不同序列（T1WI和T2WI）中“白色图像”解释不同，原因在于T1WI是记录不同组织的 纵向弛豫时间，而T2WI是记录的 横向弛豫时间。 说到弛豫时间，又 …

大家要扫描T2*WI可以先从原始序列里找，在Brain的文件夹里可以找到T2W FFE，用这个序列得到的就是梯度回波序列T2*WI。 图4：不同对比度的T2w的比较 如图所示，左图是经典自旋回波 …

The two basic types of MRI images are T1-weighted and T2-weighted images, often referred to as T1 and T2 images. The timing of radiofrequency pulse sequences used to make T1 images …

T2-weighted images are a type of magnetic resonance imaging (MRI) that highlights differences in the T2 relaxation times of various tissues. T2 relaxation refers to the decay of transverse …

T 2 *-weighted imaging is an MRI sequence to quantify observable or effective T 2 (T2* or "T2-star"). In this sequence, hemorrhages and hemosiderin deposits become hypointense. [2]

前面几篇简要介绍了 mri 设备的成像原理和结构组成，这一篇来介绍一下mri图像方面的内容，mri图像比较常见的有 t1wi 、 t2wi 以及t1+c等。在介绍t1wi和t2wi之前，需要简单介绍一 …

2023年7月27日 · Here, we disseminate a dataset of paired T1-weighted (T1w) and T2-weighted (T2w) brain MRI scans acquired at 3T and 7T. We provide a comprehensive description of the …

2024年9月1日 · T2W MRI is the only one able to detect the characteristic T2W hypointense nodules of Rathke cleft cysts. The morphology of the pituitary stalk is more precisely evaluated …

2024年2月23日 · T2W T2 Fluid-sensitive sequence T2 weighted image (T2WI) is one of the basic pulse sequences on MRI. The sequence weighting highlights differences on the T2 relaxation …
