[8] DICOM has been constantly updated and extended since 1993, with the intent that changes are backward compatible, except in rare cases where the earlier specification was incorrect or ambiguous. Some older information systems generate numbers that are thoughtof as accession numbers that are not unique. The application that generates this data often does not support DICOM, resulting in another application being added to the environment to perform DICOM wrapping and to store and retrieve the data in DICOM. It has been widely adopted by hospitals and is making inroads into smaller applications such as dentists' and doctors' offices. High Bit:Most significant bit for pixel sample data. If you wish to retrieve a study based on accession number (or anything else except those 4 identifiers). While retrieving the schedule information from the Radiology Information System, the Modality Worklist allows the images to be uniquely identified with keys matching the images with the radiology order and diagnostic reports.
