The Patient Identifiers (PIDs), in DICOM tag (0010, 0020) Patient ID, are 6 digit random numbers assigned by IMS. They are called IMS-Global-IDs. PIDs beginning with '1' are LSS images; those beginning with '2' are ACRIN images.; examples:
- 101337 is an LSS PID
- 208344 is an ACRIN PID
Prior ACRIN and LSS PIDs may be found in 2 DICOM tags: (0010, 1000) Other Patient IDs and (0013, 0040) Clinical Trial Subject ID. These prior PIDs are random 4- or 5-digit (ACRIN) or 6-digit (LSS) numbers that contain no screening site information; the LSS prior PIDs may have leading zeroes which may or may not appear unless specified that they do so.; examples:
- 2542 is an ACRIN prior PID
- 18519 is an ACRIN prior PID
- 022921 is an LSS prior PID that may also be rendered as 22921
