Parsing DICOM files in a directory with GDCM

Question

If I have a directory which contains a volumetric data from a variety of sources, say PET and a 4D CT. I know how for any given dataset to use say, vtkGDCMImageReader, to load a 3D image from a series of files. To handle multiple modalities and/or 4D datasets I am currently just manually peeking at tags and dividing up the files into lists and parsing them separately.

Is there a particularly general way of going this or even better a method within GDCM ? What I am doing seems to work but feels like a bit of a hack and there must be a proper way of doing it, I just can't seem to find it.
