Friday, November 14, 2025

• A1: 8:45am-9:00am Administrative Time
• S1: 8:45am-9:45am Checkpoint - Manifest-based Access to DICOM Objects (MADO) [1]
• S1: 9:45am-10:45am Manifest-based Access to DICOM Objects (MADO) [11 hr]
• S2: 11:00am-12:00pm Checkpoint - Imaging Diagnostic Report (IDR) - Phase 2

Profile Name: IDR Phase II

• Describe gaps in Use Case coverage

• Some expansions of both use case during discussion, but look pretty good.

• Review ALL "uncertainty points" in the evaluation. Is there a resolution plan for each?

• Yes. Noted as (UP) in the review document. Covered each.

• Do the effort points in the evaluation still seem right?

• Mostly. Given the broad scope of finding encoding, still possibility for tough issues to emerge.

• Did the Breakdown of Tasks accurately reflect the work? What extra tasks arose?

• Need to rebuild the EU-IHE Comparison Spreadsheet details.

• Describe unresolved technical issues/tasks

• Lots of “examples->coding” work to do before PC-Prep

• Describe potential practical issues

• Assuming that the patterns of grouping individual observations will scale up successfully for an entire complex findings section

• Review the open issue list. Does it feel complete

• GAP – do not have a formal Open Issue list yet. Will have it for PC-Prep

• Which open issues feel most risky; what other risks exist?

• General wide breadth of scope. It will get exercised to the extent of the examples, but tricky details will lurk. Probably just depends on iterative evolution.
• How do we characterize the scope? Final Report. All modalities.
• E.g. one well-defined example per major subspecialty (neuro CT/MR, Chest CT, Chest XR, CAP CT, MSK Trauma, MG BIRADS, Cardiac UL, Liver UL?, Onc PET, exclude Interventional (XA), )
• Note that the specs are general, the examples are specific

• How is the work fitting in the allocated bandwidth? (Time to spare? Just right? Things were left undone?)

• Mostly right.

• How does the scope feel? (Room to expand? Just right? Pretty ambitious?)

• Mostly right. A bit ambitious due to the nature of findings being a large scope, but this will be a good start.

• If you had to reduce scope, what would you drop?

• Transaction definitions; fewer examples

• Have the promised resources manifested?

• Mostly. Participation before the meeting from some CDE folks and they have committed to reviewing. Had remote participation from HL7 EU

• What tasks would benefit from additional expertise?

• will be leaning on Tarik and the CDE folks once there is concrete content to review
• would be nice to have Report Creators engaged

• What vendors are engaged for each actor? Record how many.

• Indirect Nuance participation through Tarik but need more direct engagement on all fronts. TODO
• Recruit at Radiology Reimagined: RadAI, Rad Pair (Jason), Hoppr, Jacobian (David),

• Point people to the Phase I IDR and encourage participation in Phase II
• At least target during PC - get email addresses

• Was the profile where it needed to be at the start of the Kickoff meeting (See "Kickoff Meeting" above), if not what was the gap

• Good list of topics and materials for discussion;
• Would have been nice to have a draft Profile document, but that will be here for PC Prep

• Was the profile where it needed to be at the end of the Kickoff meeting, if not what was the gap

• Uncertainty topics mostly resolved.
• Good input on concepts in general
• Would have been nice to have a draft document
• There’s going to be a lot of example work to do

• How many tcons would you like between now and the PC Prep Meeting?

• One Clinical Consult (Jan 2nd week?), One Tech Cmte (Also Jan 2nd week?)
• Kevin will reach out for CC call; cc Valerie (CDE Cmte) and Jamie (IHE)
