Evaluation of Partial Volume Correction Techniques for Sodium MRI of the Achilles Tendon
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To evaluate partial volume correction (PVC) techniques for sodium MRI of the Achilles tendon in situ and in vivo. Methods Five PVC methods were evaluated including a volume ratio of the proton and sodium segmentations (PSSR), a modified least trimmed square (3D‐mLTS) linear regression, a geometric transfer matrix (GTM) approach, a ...
