RE: Could I use Draw/Descriptive to measure ROI?
There are three descriptive lines:
 All voxels ("VOI")
 All non-zero voxels ("VOI <>0")
 All voxels with positive intensity ("VOI >0")

For each, you get the number of voxels (nvox), cubic centimeters (cc), minimum (min), mean (mean) and maximum (max) and standard deviation (SD) for the voxel intensities under the drawing...
