Energy-based Tissue Manifolds for Longitudinal Multiparametric MRI Analysis

Kartikay Tehlan, Lukas F\"orner, Matthias Wagner, Michael Fr\"uhwald, Nassir Navab, Nico Schmutzenhofer, Sina Wendrich, Thomas Wendler

A fixed energy function learned from one baseline multiparametric MRI scan tracks how voxel intensity vectors shift in sequence space during follow-up imaging.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

In a paediatric case with later recurrence, follow-up scans show progressive deviation in energy and directional displacement in sequence space toward the baseline tumour-associated regime before clear radiological reappearance.

C2weakest assumption

The baseline energy manifold learned from the initial scan accurately represents stable tissue regimes that persist and can be used to detect meaningful changes in subsequent scans without being affected by imaging variations or normal tissue evolution.

C3one line summary

A patient-specific energy manifold learned from baseline multiparametric MRI provides a geometric reference system for tracking longitudinal tissue changes through energy and displacement analysis in sequence space.
