You don't have to modify anything in gdcm code :

A image may contain uint8_t, or int8_t, or uint16_t, or int16_t, or 
uint32_t, or int32_t pixels.
A method can only return *one* data type.
If you know your images are uint16_t, just write :

  uint16_t *myImageData = (uint16_t *)myFileHelper->GetImageData();

(The pixels are *not* modified; you just tell the compiler you know 
they are 16 bits)
