Magnetic Resonance Electrical Properties Tomography (MR-EPT) for Early Cartilage Degeneration
PhD Research · MR-Based Biomarkers · University of Colorado Boulder
Problem
Existing imaging methods (T2, T1ρ, dGEMRIC - delayed Gadolinium-Enhanced MRI of Cartilage - , sodium MRI) detect degeneration only after structural or biochemical decline is advanced. There is no direct biomarker for the ionic and proteoglycan-dependent electrochemical state of cartilage.
Objective
Develop, optimize, and validate an MR-EPT pipeline to map cartilage conductivity (QCM) as an early, noninvasive biomarker of degeneration.
Methods
- Technique Development: Helmholtz-based conductivity reconstructions using B1 phase; forward simulations to optimize smoothing, Laplacian parameters, and coil assumptions
- Phantom Validation: Multi-compartment saline phantoms; magnet variability, coil reassembly, and rotation tests with 3T bSSFP - balanced steady-state free precession
- Mechanical Loading Integration: MRI-compatible knee loader; tested conductivity shifts in loaded vs. unloaded tibiofemoral cartilage
- In Vivo Scans: Feasibility in healthy volunteers; cross-sectional post-ACLR - Anterior Cruciate Ligament Reconstruction - (6 months); longitudinal 6→12 months
- Automated Analysis: Processing in MATLAB, R, and HPC clusters; integrated with T2/T2*/T1ρ and patient-reported outcomes
- Study Management: Co-managed 40-patient reconstruction cohort; recruitment, scheduling, anonymized workflows
Results
- Phantom testing confirmed repeatability across magnet sessions and setups
- Healthy volunteer scans showed consistent spatial patterns across regions and repeat sessions.
- Mechanical loading produced measurable regional shifts
- ACLR knees showed lower femoral conductivity at 6 months; partial recovery trends at 12 months
- Conductivity exhibited unique signal not captured by qMRI alone; weak-to-moderate correlations with T2/T1ρ
- Co-authored provisional patent: MRI of Electromechanics (63/855,127, 2025)
Human-Subject Relevance
QCM reflects ionic/proteoglycan-linked electrical properties of cartilage. Early human-subject results suggest it may add complementary information to standard qMRI metrics, motivating further validation and translation work.
Future Directions
- Edge-preserving reconstructions & noise suppression
- Expanded loading paradigms and motion compensation
- Multi-parametric fusion with sodium MRI and T1ρ
- Broader ACLR and OA cohorts with matched controls
- Translation to ankle, hip, and lumbar disc
- Regulatory and clinical integration for orthopedic screening
