This ensures that no files passed through the service are vulnerable to the [malicious preamble vulnerability](https://dicom.nema.org/medical/dicom/current/output/chtml/part10/sect_7.5.html). However, this also means that [preambles used to encode dual format content](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6489422/) such as TIFF can't be used with the service.
