Assessment of MRI Issues at 3 Tesla for a New Metallic Tissue Marker

Figure 2

(a) MRI artifact associated with the tissue marker on a gradient echo pulse sequence (TR/TE, 100-msec/15-msec; flip angle, 30 degrees; long axis view; artifact area, 82-mm²). The artifact appeared as a low signal intensity signal void that was relatively small in relation to the size and shape of the marker. (b) MRI artifact associated with the tissue marker on a spin echo pulse sequence (TR/TE, 500-msec/20-msec; long axis view; artifact area, 38-mm²). The artifact appeared as a low signal intensity signal void that was relatively small in relation to the size and shape of the marker. Note that the artifact size was larger for the gradient echo pulse sequence (a) compared to that observed for the spin echo pulse sequence.
