Why convert DCM to PDF?
DICOM files require specialist software to open, making them impractical to share with non-medical recipients. Exporting to .pdf produces a universally readable document that works as an email attachment, in patient portals, and in insurance or legal submissions without requiring the recipient to install a DICOM viewer.
