- W4200423079 abstract "To prospectively evaluate the clinical usefulness of Silent magnetic resonance angiography (Silent MRA) in the follow-up of endovascular-treated intracranial aneurysms by comparing it with time-of-flight magnetic resonance angiography (TOF MRA) and digital subtraction angiography (DSA).Patients with endovascular-treated saccular aneurysms and followed with Silent MRA, TOF MRA, and DSA in our center were included. The visualization of the treated sites in the two MRA sequences was assessed using a 5-point scale. The aneurysm occlusion status according to each of the three imaging modalities was assessed using a 3-point scale.Forty-one patients with 46 saccular aneurysms were recruited. The image quality score of Silent MRA was significantly higher than that of TOF MRA (4.32 ± 0.87 vs. 3.08 ± 1.48, P < 0.001). In the aneurysms treated by simple coiling, the maximal aneurysm diameter showed a strong negative correlation with image quality score in TOF MRA (Spearman's r = -0.519, P = 0.033), while it showed no significant correlation in Silent MRA (r = -0.037, P = 0.887). For the aneurysm occlusion status, inter-modality agreement was excellent (κ = 0.845) between DSA and Silent MRA, but poor (κ = 0.185) between DSA and TOF MRA.Silent MRA was superior to TOF MRA in the follow-up of endovascular-treated intracranial aneurysms and showed excellent consistency with DSA in the evaluation of aneurysm occlusion. Therefore, Silent MRA is useful for the follow-up of endovascular-treated aneurysms." @default.
