Hi all,

I'm new to using findscu / movescu. I would simply like to automate the retrieval of DICOM images from PACS. I have tried the following commands and although they give me correct answers, no files are transferred. What do you think the problem could be?
Thank you

findscu -S -k 0008,0052="STUDY" -k "PatientName=XXX" -k "AcquisitionDate=20190330" --aetitle "My_Mac_AETITLE" --call "PACS_AETITLE" PACS_IP PACS_port > cfind.result

the file find.result is empty even if I get interactively the results

movescu -S +P 4096 -k 0008,0052=IMAGE -k 0008,0052="STUDY" -k "PatientName=XXX" -k "AcquisitionDate=20190330" -aet "My_Mac_AETITLE" -aec "PACS_AETITLE" -v PACS_IP PACS_port -od "/Volumes/Dati/folder/"

Hi Domenico,

> findscu -S -k 0008,0052="STUDY" -k "PatientName=XXX" -k "AcquisitionDate=20190330" --aetitle "My_Mac_AETITLE" --call "PACS_AETITLE" PACS_IP PACS_port > cfind.result
> the file find.result is empty even if I get interactively the results

by default, findscu uses stderr for the log output and not stdout. So depending on the shell you use, you have to specify another syntax for redirecting stderr, e.g. "2>" instead of ">" for the bash.
Furthermore, newer versions of the findscu do not show the responses if the INFO logger is not enabled (option -v or -d) or the output is not enabled explicitly (option +sr).

Since you want to automate the retrieval, you might want to try one one of the --extract options:

-X --extract extract responses to DICOM file (rsp0001.dcm...)
-Xx --extract-xml extract responses to XML file (rsp0001.xml....)
-Xs --extract-xml-single [f]ilename: string
extract all responses to given XML file f

Regards,
Jörg

Does the movescu really report a successful C-MOVE? Or just "some progress"?
Typically if query succeeds but move does not, it is a configuration issue.
The MOVE-SCP establishes a C-STORE connection as a Storage SCU to the application specified by the Move Destination AET (-aet / -aem). So the SCP (PACS) needs a configuration to resolve "My_Mac_AETITLE" into IP address and TCP port.

Apart from that, your move request will be malformed the way that you put it for several reasons. Specifying the query/retrieve level twice (STUDY/IMAGE) is contradictory by itself. Furthermore, in StudyRoot Q/R MOVE it is required to specify a Study Instance UID as a matching key (and nothing else if a STUDY-move is intended).
See PS3.4, Annex C
