Solution Overview
Problem
Current methods for assessing pancreaticobiliary duct hypertension are invasive and often ineffective, leading to unnecessary interventions and complications, with no non-invasive technology available to accurately measure duct pressure.
Innovation Solution
A non-invasive method using MRI-based imaging and computational fluid dynamics to simulate pressure distribution in the pancreaticobiliary duct, allowing for quantification of hypertension and guiding intervention decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If invasive procedures (ERCP with stent placement or surgery) are performed to relieve pancreatic duct hypertension, then ductal obstruction is relieved, but the procedures have little effect on neuropathic pancreatitis and may increase harm due to complications
Solution Approach 1:
The system performs preliminary computational fluid dynamics simulation and pressure mapping before invasive procedures to predict which patients will benefit from intervention. This preliminary assessment prevents unnecessary invasive procedures in patients with neuropathic pancreatitis who would not respond to ductal decompression, thereby avoiding procedure-related complications and harm.
2Productivity
If invasive procedures are performed on all patients with chronic pancreatitis pain, then some patients may experience pain relief, but many patients undergo unnecessary interventions with no benefit
Solution Approach 1:
The system replaces the mechanical invasive measurement system (ERCP with pressure transducers) with a non-invasive computational model. By using MRI-based imaging combined with computational fluid dynamics simulation, the system predicts pancreatic duct pressure and patient response to intervention without requiring invasive procedures, thereby eliminating time loss from unnecessary interventions while maintaining accurate assessment capability.
3Ease of operation
If non-invasive technology is developed to measure duct pressure, then unnecessary invasive procedures are reduced, but currently no such technology exists
Solution Approach 1:
The system introduces computational fluid dynamics simulation as an intermediary between non-invasive MRI imaging and pressure assessment. The CFD model uses anatomical geometry from MRI images to simulate fluid flow and calculate pressure distribution in the pancreatic duct, providing accurate pressure estimates without direct measurement, thus achieving both non-invasive operation and measurement precision.

AI summary
Techniques for non-invasively assessing pancreaticobiliary duct hypertension in a patient are presented. The techniques include: obtaining a three-dimensional image of the patient's pancreaticobiliary duct; segmenting the three-dimensional image of the patient's pancreaticobiliary duct, from which a pancreaticobiliary duct geometry is obtained; specifying at least one flow rate value for the patient; computing, based on the at least one flow rate value and the pancreaticobiliary duct geometry, a relative pressure distribution along the pancreaticobiliary duct geometry; determining, based at least on the relative pressure distribution, a pancreaticobiliary duct hypertension quantification for the patient; and providing the pancreaticobiliary duct hypertension quantification for the patient.
