There is the potential for exam files being assigned duplicate Unique Identifiers (UIDs),. If the system receiving the DICOM file (e.g., Picture Archiving and Communication System (PACS)) relies solely on the UID to accept exams, this could lead to a mismatch of the patients identification with their physiological data.
