Objective: As the use of medical images in applications other than direct patient care increases, the need for deidentified images grows. Federal regulations govern the requirements for deidentification, and software developers offer several methods for deidentification.
Conclusion: However, there are numerous ways for protected health information to be included in images other than in DICOM headers. Either such information must be obscured or the images containing the information must be deleted to comply with deidentification requirements.
