Fig. 1. Images of a 58-year-old male with a treated aneurysm in the left MCA bifurcation.

A. Stent-assisted coil embolization was performed with a Neuroform Atlas stent. Arrowheads indicate the implanted stent marker. B. Final angiography during the embolization procedure shows the neck remnant (arrow) of the aneurysm sac. C. Time-of-flight MRA shows poor visualization at the stented segment of MCA (arrowheads), and the neck remnant is not depicted (arrow). D. Silent MRA shows excellent visualization at the stented segment (arrowheads), and the neck remnant is fully depicted (arrow). MCA = middle cerebral artery, MRA = MR angiography
