Erdas Imagine has an add-on called DeltaCue that is designed for this type of analysis. Some of the highlights include:
In my company we are using Definiens Developer http://developer.definiens.com/ for checking changes in time, ie Open Lands, woodland losses (illegal fellings, windblows, etc), new plantings… This software is also being used in oncology so don’t be surprised.

You cite ArcGIS and Erdas. Any of those software could help, but I would rather use Erdas than ArcGIS for remote sensing application (and if you want to use ArcGIS, you need the spatial analyst extension).
For other softwares, your should consider QGIS, with GRASS or OTB (free and open source) as well as ENVI or Definiens.
