Get PET imagem from PACS

[jaborgesBR]

Hello, I am trying to get DICOM imagem from Osirix using qrscp.py of pynetdicom. For CT images it works fine, but I don't have sucess with Nuclear Medicine images. Does anyone can give me a tip? What modifications Do I need to do in qrscp.py? I want specificly getting PET series. Thanks in advance.

Hi, do you get an error or just nothing? Does the find return some result? I don't see any reason why it would work for CT images and not for PET images ...

Did you change the folowing line?:

file_meta.MediaStorageSOPClassUID = '1.2.840.10008.5.1.4.1.1.2'

otherwise I think that you will only be able to store CT images that are sent back to you.

I have tried, without success...

[Patrice Munger]

And if you try to only retrieve the CT series, it works?

Yes. It woks with ct series.

[Patrice Munger]

It looks like the server does not even initiate the store operation ... Could it be something in the servers configuration?

Yes. It woks with ct series.

I have tried sending NM series after running Storage SCP example and received the following error from OsiriX: "DICOM Network Failure. SCU failed 6:0203 DIMSE Badly formed message". When I sent CT images, no problems. Any idea?

You are sending from Osirix to your pynetdicom SCP or the other way around?

Just a note, I had difficulty collecting images from an MRI scanner a while ago (error was badly formed request or something), and it ended up being because I was using the stable version from pip. The current development version on Github fixed the problem.

[smen...@gmail.com]

*Resent since the last post included email addresses in the reply*

Clone (or download the zip from) the latest version here:
https://github.com/patmun/pynetdicom

Uninstall version 0.8.1 (hasn't been updated since 2014) from pip using "pip uninstall pynetdicom". Then open a command prompt in the downloaded directory and run either "python setup.py install" or "python setup.py develop" (whichever one you prefer), and that's it. You now should have the latest development version.

[jaborgesBR]

Dear smen,

Could you give me more details? I am using pip version 9.0.1.

Thanks in advance

Dear Steven,

I have installed pydicom 1.0.0 and pynetdicom (downloading it from https://github.com/patmun/pynetdicom).

When I run qrscu file, following error appear:

"  File "qrscu.py", line 15, in <module>

    from netdicom.applicationentity import AE

  File "/Users/jaborges/anaconda/lib/python2.7/site-packages/pynetdicom-0.8.1-py2.7.egg/netdicom/__init__.py", line 7, in <module>

    from applicationentity import AE

    from dicom.filereader import read_dataset

ImportError: cannot import name read_dataset"

Any ideia?

[Patrice Munger]

You need pydicom 0.9.9, not 1.0.0. "pip install pydicom" should install the right version.
