MRI of wrist ligament trauma was similar at 7 T and 3 T with arthroscopy as a reference standard.

ABSTRACT:

Objectives

The aim was to compare the diagnostic accuracy of magnetic resonance imaging (MRI) at 7 Tesla (T) and 3 T in patients with clinically suspected injury of the triangular fibrocartilage complex (TFCC) or the scapholunate ligament (SLL) using wrist arthroscopy as a reference standard.

Methods

Twenty-four patients scheduled for wrist arthroscopy due to suspected TFCC or SLL injury were examined with 7-T and 3-T MRI before arthroscopy. Four musculoskeletal radiologists independently evaluated the MR examinations in randomized order, and the findings were compared to those at wrist arthroscopy.

Results

Sensitivity, specificity, and accuracy for TFCC injuries were 0.85, 0.68, and 0.82 for 7 T and 0.75, 0.73, and 0.77 for 3 T, respectively. For SLL injuries, the co
