The Content-Type header field specifies the media type of the payload. It shall only be present when a payload is present, and any media type parameters shall specify the encoding of the corresponding message part.

In particular, a DICOM Media Type used as the value of a Content-Type header field shall have zero or one Transfer Syntax parameter (see Section 8.7.3.5.2), and zero or one charset parameter (see Section 8.7.3.5.3), which corresponds to the character encoding of the corresponding message part.

Content-Type: dicom-media-type +transfer-syntax-mtp +charset-mtp

If there is a conflict between the Transfer Syntax specified in the media type and the one specified in the File Meta Information Transfer Syntax UID (0002,0010) Attribute, the latter has precedence.
