Hi Kevin,


      Yes,
      the value should be in Hounsfield units,


   ...unless someone has been tampering with the image...


Before you start relying on that information you must verify
some of the values against know CT values of specific tissues.


      You can use the following table as a guide:

   Regards,


      Luis
