Binary attributes are written in hexadecimal with a preceding "0x" and
numeric string attributes are written in decimal as they are encoded, unless
the -decimal option is specified.
The attribute values, description and verbose output go to standard error.
The basic input switches are described in dcintro(1). Options specific to this
Display the tag, name, value representation
and value length of the attribute.
Display the keyword of the attribute, and
equals sign, and then the value, for use in scripts that automatically extract
multiple values in the same dckey invocation. Implies -noerror.
Attempt to extract key values even if errors
encountered whilst parsing DICOM file.
Do not report an error if the requested
attribute was not found, just an empty value or line. Implied by -brief.
Display the first (or only) value of a numeric
attribute as a decimal value.
- -k|key elementname|(0xgggg,0xeeee)
Add a key to the list of attributes to be
extracted. The attribute may also be specified as a hexadecimal pair of the
form (0xgggg,0xeeee), which also allows private attributes to be
Show the name of the file supplied in the
arguments; a hyphen will be reported if no filename was supplied.

Attempts to extract sequences or OB,OW attributes may fail nastily.
The order in which the attributes are extracted and written is not the same
order as they are specified on the command line, and should not be depended
The -describe and other options cannot be used at the same time.
The -decimal option uses a double conversion before displaying the value and
there may be sign extension and precision issues with some values.
The reading of the attributes from the DICOM file will not proceed past the top
level Pixel Data attribute, in order to accelerate the speed of reading.
