Yes & No. There is no way to be sure you are allowed to keep the same
Instance UID. I'll assume you know what you are doing. Anyway the
default is to always regenerate them which is safe in 100% cases.

See  itk::GDCMImageIO::KeepOriginalUIDOn  	(   	  	 )   	
http://public.kitware.com/Insight/Doxygen/html/classitk_1_1GDCMImageIO.html#itk_1_1GDCMImageIOz1844_2

But again you should really think twice before doing this.
