| Building 3d Volumes from MRI DICOM |
3D Volume Rendering is not just a graphic aid for trial like a medical illustration, but an actual clinical tool. Segmentation of an MRI image involves the clear delineation of organs and features.
3D Volume Rendering is becoming essential for displaying CT and MRI results as the images can be visualized and understood by non-radiology physicians and laymen easily.
But as its new to the legal community, 3D Volume rendering has been admitted as evidence at trial on numerous occasions and has yet to be excluded. As it involves medical illustrations and animations together hence this technology is encountering initial objections that will be overcome easily in near future.

In almost all cases, MRI images have a slice thickness far greater than their in-plane resolution, making multiplanar reconstruction meaningless. Also, most MRI images have a gap between the slices, which also renders multiplanar meaningless and impossible (unless you're happy with black bars where the slice gaps exist).
You can look at your images and the slice thickness is on the graphics. the slice gap is usually not displayed, but if you look at the slice location displayed on adjacent slices, and compare to the slice thickness, you can easily compute the slice gap.
The in-place resolution is (approx) the field of view divided by the acquisition matrix, both of which are also printed on the image somewhere.
By the way, if you have the dicom (.dcm) files, there is lots of data that's 'hidden' that you can access with a full featured dicom file editor.

| 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.
