All you need is

typedef itk::Image<PixelType, Dimension> ImageType;
typedef itk::ImageFileReader <ImageType> ReaderType;
ReaderType::Pointer reader = ReaderType::New();
reader.SetFilename(inputFilename);
reader->Update();

// The ImageFileReader class determines the image format from the file 
extension and then points to the approrpriate ImageIO

There is a whole chapter on data representation  in the ITK software 
guide. You might want to take a look at that for detailed explanation.

and there are several IO examples in the main source tree
