As MR angiography cannot demonstrate vessel wall, vessel
wall imaging is important to detect vulnerable
atherosclerotic plaque. The goal of this study was to
evaluate feasibility of T1 SPACE to detect intracranial
atherosclerosis in nonsymptomatic patient. Twenty
nonsymptomatic patients underwent both TOF and T1 SPACE
using 3.0 Tesla MR system were enrolled.TOF-source was
considered as a reference standard for lumen of
intracranial arteries. We measured luminal area of
basilar artery and both cavernous internal carotid
arteries on T1 SPACE and TOF source and vessel wall
thickness by subtracting luminal diameter on TOF-source
from outer diameter on T1-SPACE.Vessel areas measured
from TOF-source and T1 SPACE showed significant linear
correlation.However,there was no correlation between
atherosclerotic risk factors and vessel wall thickness.
