The Dicom Toolkit (DCMTK) from Offis (http://dicom.offis.de/) can do
this. These are many command line utilities, available for Win32,
Linux and Solaris in binary format, and as well as source code. What
you need is the dcmdjpeg utility.

wonko@weird wonko $ dcmdjpeg --help
$dcmtk: dcmdjpeg v3.5.2 2002-12-23 $

dcmdjpeg: Decode JPEG-compressed DICOM file
usage: dcmdjpeg [options] dcmfile-in dcmfile-out

parameters:
dcmfile-in DICOM input filename to be converted
dcmfile-out DICOM output filename

general options:
-h --help print this help text and exit
--version print version information and exit
-v --verbose verbose mode, print processing details
-d --debug debug mode, print debug information
processing options:
color space conversion options:
+cp --conv-photometric convert if YCbCr photom. interpr. (default)
+cl --conv-lossy convert YCbCr to RGB if lossy JPEG
+ca --conv-always always convert YCbCr to RGB
+cn --conv-never never convert color space
planar configuration options:
+pa --planar-auto automatically determine planar configuration
from SOP class and color space (default)
+px --color-by-pixel always store color-by-pixel
+pl --color-by-plane always store color-by-plane
SOP Instance UID options:
+ud --uid-default keep same SOP Instance UID (default)
+ua --uid-always always assign new UID
output options:
output file format:
+F --write-file write file format (default)
-F --write-dataset write data set without file meta information
output transfer syntax:
+te --write-xfer-little write with explicit VR little endian (default)
+tb --write-xfer-big write with explicit VR big endian TS
+ti --write-xfer-implicit write with implicit VR little endian TS
post-1993 value representations:
+u --enable-new-vr enable support for new VRs (UN/UT) (default)
-u --disable-new-vr disable support for new VRs, convert to OB
group length encoding:
+g= --group-length-recalc recalculate group lengths if present (default)
+g --group-length-create always write with group length elements
-g --group-length-remove always write without group length elements
length encoding in sequences and items:
+e --length-explicit write with explicit lengths (default)
-e --length-undefined write with undefined lengths
data set trailing padding (not with --write-dataset):
-p= --padding-retain do not change padding
(default if not --write-dataset)
-p --padding-off no padding (implicit if --write-dataset)
+p --padding-create [f]ile-pad [i]tem-pad: integer
