2. The Problem

<Summarize the integration problem. What doesn’t work, or what needs to work.>

To extend IHE's capabilities that enable our radiology end-users to demand Enhanced MR/CT implementations, I propose implementating Cardiac Imaging and Multi-stack Spine Imaging this year and Spectroscopy next year.

  • Enhanced DICOM objects contain more and better defined attributes that increase interoperability.
  • The rate of implementation of Enhanced DICOM will strongly depend on user demands for display capabilities. Display vendors, willing to implement the support for Enhanced DICOM SOP Classes, will benefit in the selection of their basic functionality by the existence of the IHE Profiles.


3. Key Use Case

<Describe a short use case scenario from the user perspective. The use case should demonstrate the integration/workflow problem.>

Cardiac Imaging should address anatomical and functional Cardiovascular CT and MR imaging for non-gated, prospective gated, retrospective gated examinations.

It might be that sub-profiles for these cases are required by clinical groups and if so the work must be divided over more years. An initial profile with limited functionality is certainly in scope.

Creating/promoting a CARDIO profile will enable public discussion on the need for display of running and/or synthesized ECGs together with the images for standard (non specialized) workstations.

<Feel free to add a second use case scenario demonstrating how it “should” work. Try to indicate the people/systems, the tasks they are doing, the information they need, and hopefully where the information should come from.>


4. Standards & Systems

The NEMA Taskforce for Enhanced CT/MR has already provided in 2005 test scenario's for Cardiac Imaging, Multi Stack Spine Imaging and Spectroscopy and draft specifications similar to those used to kick-start DIFF and PERF.

5. Discussion

In follow-up to the creation of the DIFF and PERF profiles it is important to keep the momentum for the creation of more clinical profiles that support the implementation of Enhanced MR and CT.

Testing PERF at the 2010 Connectathon may reveal issues that could be efficiently addressed in parallel in the CARDIO profile.

The profile would follow the pattern established by DIFF and PERF.

The dimension module requirements are most likely identical to those of the PERF profile.

Cardiology might be interested, but radiology needs to be involved too.
