Visualization score of the flow in stent: 1, not visible (almost no signal in the stent); 2, poor (structures are slightly visible but with significant blurring or artifacts, not diagnostic); 3, good (good-quality diagnostic information with minimal blurring or artifacts); 4, excellent (excellent-quality diagnostic information; the shape of depiction is nearly equal to that of DSA).

Acom: anterior communicating artery; BF: body filling; CO: complete occlusion; ICA: internal carotid artery; N/A: not available; NR: neck remnant; Pcom: posterior communicating artery; PETRA: pointwise encoding time reduction with radial acquisition; SAC: stent-assisted coil embolization; TOF: time-of-flight; UE: unevaluable
