An imaging report records the radiologist's written conclusion. Original DICOM files contain the full image data from CT, MRI, PET-CT, and similar studies. Doctors may need the images to assess location, extent, or changes over time.
You can still begin an inquiry with the report alone. Explain where the original images are stored. They may be on a disc, patient portal, QR code, or download link. The hospital considers the condition, image date, and quality. It then decides whether DICOM files or new testing are needed. Do not repeat scans on your own.
