cutLoadPGMub from Cutil.h - Replacement for Cuda8

I'm trying to read and load an image using cutLoadPGMub method under cutil.h header. But unfortunately i'm using Cuda8 for my development. Having this into account, i found out that cutil.h was last deprecated in Cuda5. Can anyone tell me what is the replacement for cutLoadPGMub method and Cutil.h library for Cuda8?

Thanks.
