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.
