| 1. | Proton weighted image , pw
质子密度加权像 |
| 2. | The following is a general guide to how tissue appears on t1 - or t2 - weighted images
以下是一个各种组织分别在t1及t2加权像上如何显现的简要介绍。 |
| 3. | Transient ischemic attack with abnormal diffusion - weighted imaging results : what ' s in a name
伴异常弥散加权像结果的短暂性脑缺血发作：名称的含义？ |
| 4. | Note how the conventional t2 - weighted images have converted to high signal in the lesion at four days after onset of symptoms
注意发病4天后病变区域在常规t2 -加权像转变成高信号。 |
| 5. | Ct demonstrates the calcification , and the " scalloped " ventricular wall can also be seen well with t1 - weighted mr
Ct显示脑室壁有钙化改变，磁共振t1加权像上可清楚看到“干贝样”变化。 |
| 6. | The infarct also has high signal on the t2 - weighted images . this slice also demonstrates the ribbon - like geometry of the lesion
在t2加权像上，梗塞灶也呈高信号。此层面损害区域同样呈带状。 |
| 7. | The mr demonstrates an area of mixed signal intensity on proton density ( pd ) and t2 - weighted ( t2 ) images in a right parietal - occipital region
磁共振t2加权像及质子密度像均显示在右侧顶枕区有一混合强度区域。 |
| 8. | Acutely ( within hours of the ictus ) , the t1 - weighted images usually demonstrate abnormally low signal ; the t2 - weighted images abnormally high signal
急性期(发病数小时内) , t1加权像显示异常低信号； t2加权像显示异常高信号。 |
| 9. | When deformable models are used to extract brain contour from head mri t2 images , local minimums largely affect the algorithm ' s converging to the global minimum
在提取人头部磁共振图像t2加权像的横断面的脑轮廓时，因为在图像内部存在许多的局部极小值，严重的影响了算法向全局极小收敛。 |
