In addition to the DICOM Image and Image related SOP Classes (e.g., results, patients) other SOP Classes tailored for media storage may be used to provide references (or directories) based on medical information, thus facilitating access to the clinical imaging information. Such a SOP Class is the Media Storage Directory SOP Class as defined in PS 3.4 of the DICOM Standard. Instances of this SOP Class are conveyed in the File with a File ID of DICOMDIR.
