Qualitative image artifacts. MR imaging findings in a volunteer with the RFID tags positioned on the dorsum of the wrist (a, b) and on the volar aspect of the wrist (c, d). Axial T1-weighted spin-echo MR-image (600/13; number of signals acquired, 1; field of view, 90 mm) shows only minimal geometric distorsion and susceptibility artifacts on skin and underlying subcutaneous tissue (arrowheads) (a and c). Axial T2-weighted Flash2D gradient-echo MR-image (400/15; number of signals acquired, 2; field of view, 90 mm) shows increased susceptibility artifacts on skin and underlying subcutaneous tissue and tendons (arrows) (b and d). Interpretation of articular structures is not compromised.
