abstract = {Background Ultrahigh-field-strength MRI at 7 T may permit
superior visualization of noninflammatory wrist pathologic
conditions, particularly due to its high signal-to-noise
ratio compared with the clinical standard of 3 T, but direct
comparison studies are lacking. Purpose To compare the
subjective image quality of 3-T and 7-T
ultrahigh-field-strength wrist MRI through semiquantitative
scoring of multiple joint tissues in a multireader study.
Materials and Methods In this prospective study, healthy
controls and participants with chronic wrist pain underwent
3-T and 7-T MRI (coronal T1-weighted turbo spin-echo [TSE],
coronal fat-suppressed proton-density [PD]-weighted TSE,
transversal T2-weighted TSE) on the same day, from July 2018
to June 2019. Images were scored by seven musculoskeletal
radiologists. The overall image quality, presence of
artifacts, homogeneity of fat suppression, and visualization
of cartilage, the triangular fibrocartilage complex (TFCC),
and scapholunate and lunotriquetral ligaments were
semiquantitatively assessed. Pairwise differences between 3
T and 7 T were assessed using the Wilcoxon signed-rank test.
Interreader reliability was determined using the Fleiss
kappa. Results In total, 25 healthy controls (mean age, 25
years ± 4 [SD]; 13 women) and 25 participants with chronic
wrist pain (mean age, 39 years ± 16; 14 men) were included.
Overall image quality (P = .002) and less presence of
artifacts at PD-weighted fat-suppressed MRI were superior at
7 T. T1- and T2-weighted MRI were superior at 3 T (both P <
.001), as was fat suppression (P < .001). Visualization of
cartilage was superior at 7 T (P < .001), while
visualization of the TFCC (P < .001) and scapholunate (P =
.048) and lunotriquetral (P = .04) ligaments was superior at
3 T. Interreader reliability showed slight to substantial
agreement for the detected pathologic conditions (κ =
0.20-0.64). Conclusion A 7-T MRI of the wrist had potential
advantages over 3-T MRI, particularly in cartilage
assessment. However, superiority was not shown for all
parameters; for example, visualization of the triangular
fibrocartilage complex and wrist ligaments was superior at 3
T. © RSNA, 2023 Supplemental material is available for this
