This function is a pared down version of :func:`~pydicom.filereader.read_preamble` meant for a fast return. The file is read for a conformant preamble ('DICM'), returning ``True`` if so, and ``False`` otherwise. This is a conservative approach. Parameters ---------- file_path : str The path to the file.
