abstract = {To analyze regional variations in T2 and T2* relaxation
times in wrist joint cartilage and the triangular
fibrocartilage complex (TFCC) at 3 and 7 T and to compare
values between field strengths.Twenty-five healthy controls
and 25 patients with chronic wrist pain were examined at 3
and 7 T on the same day using T2- and T2*-weighted
sequences. Six different regions of interest (ROIs) were
evaluated for cartilage and 3 ROIs were evaluated at the
TFCC based on manual segmentation. Paired t-tests were used
to compare T2 and T2* values between field strengths and
between different ROIs. Spearman's rank correlation was
calculated to assess correlations between T2 and T2* time
values at 3 and 7 T.T2 and T2* time values of the cartilage
differed significantly between 3 and 7 T for all ROIs (p ≤
0.045), with one exception: at the distal lunate, no
significant differences in T2 values were observed between
field strengths. T2* values differed significantly between 3
and 7 T for all ROIs of the TFCC (p ≤ 0.001). Spearman's
rank correlation between 3 and 7 T ranged from 0.03 to 0.62
for T2 values and from 0.01 to 0.48 for T2* values. T2 and
T2* values for cartilage varied across anatomic locations in
healthy controls at both 3 and 7 T.Quantitative results of
T2 and T2* mapping at the wrist differ between field
strengths, with poor correlation between 3 and 7 T. Local
variations in cartilage T2 and T2* values are observed in
healthy individuals.T2 and T2* mapping are feasible for
compositional imaging of the TFCC and the cartilage at the
wrist at both 3 and 7 T, but the clinical interpretation
remains challenging due to differences between field
strengths and variations between anatomic locations.•Field
strength and anatomic locations influence T2 and T2* values
at the wrist. •T2 and T2* values have a poor correlation
between 3 and 7 T. •Local reference values are needed for
each anatomic location for reliable interpretation.},
