altered resolution metadata

Is it possible for the 'getMetadata("Info") or 'getImageInfo()' macro commands to alter image properties?  
 TEM negatives were scanned on an Epson scanner and saved in Adobe Photoshop CS3.  The scans open in ImageJ
with correct scan resolution, 600 or 1200 dpi, displayed in the Image Info window.  But, after reading strings from metadata on several open images, the dpi will change from "Resolution: 600 pixels per inch" to something like "231.50 pixels per microns" or "399.99 pixels per microns".  And only in a single image, not all of the open images.

I'm not writing anything, only reading.  Is there anyway to keep this from happening?  
Thanks,
Glen
