| T1&T2 WAIGHTED MEANING ? |
All MRI images have contrast (the bright and the dark) that is based on properties of the tissue that's being imaged. In MRI (unlike, for example, CT) those images are based on a combination of several physical properties. So to some extent ALL MRI images are based partly on property A, property B, etc.
The tissue properties that are referred to include proton density (how many hydrogen nuclei are in a given area), motion, and two other properties that are called T1 and T2. These are properties that can be seen onloy by using the MRI instrument, much as without a microscope one cannot see inside a cell.
A T1 weighted image is one in which the differences between T1 properties of the various tissues are the predominant reason why some parts of the image are bright and others are not as bright.
This is medically useful because, since T1 and T2 are distinct properties, diseased tissue may show up different than normal tissue on either the T1 weighted scan or the T2.

We maintain the MagneVu systems and have several avaialable for sale, cheap. They are probably not a good option for veterainary work, however, becaseu the field fo view is very small. There are other inexpensive MRIs (which we also have) that will work far better.

| Dynamic data of MRI |
i almost forgot this post, but the data are still desired! i'm in the research of dynamic mri reconstruction algorithms, maybe we can communicate someday, my email: yingjie.mei@gamil.com.
Thx for ur help.

| How to fill the K-space? |
Hi,
i've been learning MRI for some weeks, and i really want to know that when we use the spin-echo sequences, how can we fill the data into K-space line by line?
i learned the steps of spatial encoding, but i need the algorithm, or the equations, or the quantitative way to fill the K-space.
thanks a lot!
