Yes it should work. No this is not limited to this only combination.

late ? do you mean slow ?
you need to split this in two operation to determine what you call
slow: write a piece of code that load a DICOM and return. Write a
script that load a png file and start a vtkImageViewer, and benchmark
both.

gdcm is much faster in Release mode AFAIK since it remove the pre/post
conditions written using asserts.
