The Gender Identity Sequence (0010,0041) and Person Names to Use Sequence (0010,0011) are potentially useful for patient reconciliation activities to find all the patient records. When patient names change or might be recorded differently at different times and locations, patient reconciliation can be difficult. These Sequences may provide a history of prior names and genders for use by reconciliation algorithms.

These Sequences might also be deliberately truncated or restricted for patient privacy reasons.

DICOM does not specify or make recommendations for how the local policies, procedures, and reconciliation algorithms should be designed.
