Why ct secondary is never kept open?

CT (Computed Tomography) secondary, or secondary reconstruction images, are not kept open primarily due to privacy and security concerns. Keeping these images accessible could lead to unauthorized access to sensitive patient information. Additionally, the storage and management of such data require significant resources and can complicate compliance with health regulations, such as HIPAA. Thus, to protect patient confidentiality and ensure efficient data management, secondary images are typically not retained.
