A
comprehensive assessment of cartilage function may use multiple quantitative
techniques such as T2, T1ρ, and dGEMRIC, and may follow the subject over
multiple time points. The purpose of
this study was to develop a semi-automated technique to generate accurate and
reproducible line profiles along the joint surface of the knee for T2,
T1ρ, and dGEMRIC to permit direct registration, comparison, and
correlation between functional cartilage imaging methods. This work
demonstrates the feasibility of an edge-based line growing technique to
generate anatomical correspondence between multiple modalities and time
points to directly correlate and contrast the measurements from each.
