Key Investigators
- BWH: Andrey Fedorov
- GE: Jim Miller
Project Description
Objective
- debug and test the pharmacokinetic modeling extension on prostate DCE MRI data
Approach, Plan
- previously validated non-open-source implementation of the PK modeling will be used as reference for comparison with the results produced by PkModeling extension
- prostate DCE MRI data will be used for testing using identically defined AIF
- success will be achieved if the results produced by PkModeling and the reference software agree
Progress
- The main source of the inconsistency was due to different models used by the two tools being compared: 2-parameter (Ktrans+ve) vs 3-parameter (Ktrans+ve+fpv). After fixing this, the results were very similar (difference <1% vs 1000%).
- Bolus arrival time was not estimated in the Slicer PkModeling tool.
- We may need to re-engineer the module to accommodate multiple models. Further discussions are needed.
