The media type shall be 'application/dicom', as specified in [RFC3240]. Payload

The transfer-syntax and charset media type parameters are forbidden in the request.


WADO-URI user agents may not depend on the presence of transfer syntax and charset media type parameters, since these have been absent since the inception of the service and are forbidden, even though this is different from the approach used by the later introduced WADO-RS service, which returns transfer-syntax and charset media type parameters in the response. The Transfer Syntax used can be determined from the PS3.10 File Meta Information.
