ACR/NEMA DICOM PS3 ... DICOM PS3 - Describe DICOM file content

## NAME

dcdump - ACR/NEMA DICOM PS3 ... DICOM PS3 - Describe DICOM file content

## SYNOPSIS

**dcdump** \[ **-v\|verbose** \] \[ **-filename** \]

## DESCRIPTION

**dcdump** reads the named dicom or acr-nema input file and describes the information contained, attempting to interpret the structure of the message, including nested sequences (cf. andump).

The group and element number, dictionary and explicit value representation, description of tag, value length and value of the element are displayed,  optionally with an offset byte count from the start of the file.

## OPTIONS

The attribute values, description and verbose output go to standard error.

Binary attributes are written in hexadecimal with a preceding "0x". Numeric string attributes are written in decimal. Attribute values are displayed in hexadecimal or string format as determined by the value representation.

The basic input switches are described in [dcintro(1)](/dcintro/1.md). Options specific to this program are:

- **-verbose**

  Display byte offset from file start and message start, in hexadecimal, and dump contents while reading and once read.

- **-filename**

  Show the name of the file supplied in the arguments; a hyphen will be reported if no filename was supplied.
