NASAView and raw MGS topography data, How to create images with the full sample size?

I am toying around with some raw image data from MGS in the form of pds files. (EDIT: MOLA instrument images). I have downloaded the data from here:

http://pds-geosciences.wustl.edu/missions/mgs/megdr.html

Each image consists of a pair of files: ".img" and ".lbl". The img-file contains the data and the lbl file contains metadata. In this metadata file it says that the sample size is 16 bits. But in the program NASAView, which one uses to generate images from pds files, I have only managed to create 8 bit images.

Is it possible to create images with the full 16 bit data with NASAView? Or should I use some other program? Or do I have to write it myself?

Thanks for any suggestions!
