AFNI program: dicom_hdr
Output of -help
Usage: dicom_hdr [options] fname [...]
Prints information from the DICOM file 'fname' to stdout.
Multiple files can be given on the command line.
OPTIONS:
-hex = Include hexadecimal printout for integer values.
-noname = Don't include element names in the printout.
-sexinfo = Dump Siemens EXtra INFO text (0029 1020), if present
(can be VERY lengthy).
-mulfram = Dump multi-frame information, if present
(1 line per frame, plus an XML-style header/footer)
[-mulfram also implies -noname]
-v n = Dump n words of binary data also.
-no_length = Skip lengths and offsets (helps diffs).
-slice_times = Show slice times from Siemens mosaic images.
-slice_times_verb = Same, but be more verbose about it.
(multiple uses increases verbosity)
(can dump CSA data)
-siemens_csa_data = same as 3 -slice_times_verb opts
Based on program dcm_dump_file from the RSNA, developed at
the Mallinckrodt Institute of Radiology. See the source

SOME SAMPLE OUTPUT LINES:
0028 0010 2 [1234 ] // IMG Rows// 512
0028 0011 2 [1244 ] // IMG Columns// 512
0028 0030 18 [1254 ] // IMG Pixel Spacing//0.488281\0.488281
0028 0100 2 [1280 ] // IMG Bits Allocated// 16
0028 0101 2 [1290 ] // IMG Bits Stored// 12
0028 0102 2 [1300 ] // IMG High Bit// 11
* The first 2 numbers on each line are the DICOM group and element tags,
in hexadecimal.
* The next number is the number of data bytes, in decimal.
* The next number [in brackets] is the offset in the file of the data,
in decimal. This is where the data bytes start, and does not include
the tag, Value Representation, etc.
* If -noname is NOT given, then the string in the '// ... //' region is
the standard DICOM dictionary name for this data element. If this string
is blank, then this element isn't in the dictionary (e.g., is a private
tag, or an addition to DICOM that the program doesn't know about, etc.).
* The value after the last '//' is the value of the data in the element.
* In the example above, we have a 512x512 image with 0.488281 mm pixels,
with 12 bits (stored in 16 bits) per pixel.
* For vastly more detail on DICOM standard, you can start with the
documents at ftp://afni.nimh.nih.gov/dicom/ (1000+ pages of PDF)!
* Also see program dicom_hinfo -- which will print out just a few user-chosen
values for each input file. It can be used in a script to sort through
a lot of files at once.
