E: No presentation context for 'CT Image Storage' has been accepted by the peer with 'JPEG 2000 Image Compression' transfer syntax for the SCU role

Does anyone know how to resolve this issue, I'm trying to push all Dicom images to PACS from a directory, the dcm images have the transfer syntax (0002,0010) Transfer Syntax UID 1.2.840.10008.1.2.4.91 (JPEG 2000 Image Compression)

from pydicom import dcmread
import os
from pynetdicom import AE, debug_logger
from pynetdicom.sop_class import CTImageStorage
import argparse

def push_to_pacs(directory, pac_addr, pacs_port):

    debug_logger()
    ae = AE()
    ae.add_requested_context(CTImageStorage)
    assoc = ae.associate(pac_addr, pacs_port)

    if assoc.is_established:
        # Use the C-STORE service to send the dataset
        for _, _, files in os.walk(directory):
            for file in files:
                try:
                    ds = dcmread(os.path.join(directory, file))
                    status = assoc.send_c_store(ds)

                    # Check the status of the storage request
                    if status:
                        # If the storage request succeeded this will be 0x0000
                        print("C-STORE request status: 0x{0:04x}".format(status.Status))
                    else:
                        print(
                            "Connection timed out, was aborted or received invalid response"
                        )
                except Exception as ex:
                    print(ex)

        # Release the association
        assoc.release()
    else:
        print("Association rejected, aborted or never connected")

if __name__ == "__main__":t
    parser = argparse.ArgumentParser(description="Process a directory.")
    parser.add_argument("--directory", required=True, help="Path to the directory")
    args = parser.parse_args()
    directory_path = args.directory

    push_to_pacs(
        directory=directory_path,
        pac_addr="localhost",
        pacs_port=8050,
    )

Any possible workaround?

You need to add CT Image Storage as a requested context with a matching transfer syntax (i.e. JPEG 2000). AE.add_requested_context() defaults to the native transfer syntaxes only. This is all explained in the user guide.

thanks, had to add the following transfer syntax

ae.add_requested_context(CTImageStorage, JPEG2000)
