FIG 2. Images of a stented and coiled arterial segment suspended in a saline and gadolinium solution within a 10-mL syringe. A spin-echo T1-weighted image (A) shows the syringe with stented vessel (white arrow) and adjacent coil mass (white arrowhead). The gradient echo image (B) shows signal intensity loss from susceptibility effects of the coil mass (blooming, white arrow), but no visible effects from the stent. Field mapping (C) shows no apparent field distortion related to the stent or the coil mass. The concentric lines represent magnetic field-strength lines with a difference of 50 Hz between lines.
