abstract = {To evaluate partial volume correction (PVC) techniques for
sodium MRI of the Achilles tendon in situ and in vivo.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 single target correction
(STC), and a novel estimated single target correction
(eSTC). Their performance was tested using simulated data
and 3 T MR data of two volunteers' Achilles tendons acquired
at different resolutions: 1.5, 2.0, 3.0, and 4.5 mm3. Since
there was no in vivo ground truth, the highest-resolution
apparent tissue sodium contents (aTSC) were used.In the
simulation, all PVC methods reduced the difference between
the actual and calculated concentrations and were 11.69 ±
6.17 mM without PVC, 4.90 ± 5.40 mM with the PSSR, 4.86 ±
5.19 mM with the mLTS, 1.72 ± 4.13 mM with the GTM, 0.36 ±
1.77 mM with STC and 0.26 ± 1.63 mM with the eSTC. In vivo,
the difference in aTSCs between the lower and the highest
resolution decreased with all PVCs ranging from 3.6 to 38.8
mM without PVC, 2.8-20.4 mM with PSSR, 4.5-25.9 mM with
mLTS, 0.9-7.8 mM with GTM, 0.1-23.8 mM with STC, and 0.7-7.7
mM with eSTC.PVC generally improved the accuracy of aTSC
calculations. The newly introduced eSTC produced the most
accurate results for the Achilles tendon.},
