The DICOM standard allows for an Encapsulated PDF in a DICOM file. Given your question, I created a sample channel that receives an HL7 MDM message with a base64 encoded PDF.
The result is a DICOM file with the demographics and other tags populated based on the MDM message.
message = qie.createDICOMMessage();
/*
The tags required for a DICOM Encapsulated PDF was taken from here:
