Abstract

Three-dimensional time-of-flight magnetic resonance angiography (3D TOF-MRA) is widely used for non-invasive postoperative follow-up after cerebral aneurysm treatment. However, susceptibility artifacts from metallic clips or coils can cause apparent parent artery signal loss or missed detection of recanalization. This study aimed to evaluate whether optimization of the frequency-encoding direction improves diagnostic reliability compared with conventional 3D TOF-MRA.
