Abstract：Objective To investigate the clinical value of three-dimensional arterial spin labeling (3D-ASL) combined with magnetic
resonance angiography (MRA) in the diagnosis of transient ischemic attack (TIA). Methods Thirty-six patients with TIA who were
admitted to our hospital were enrolled. All patients underwent routine MR examination, DWI, MRA and 3D-ASL examination. Two
doctors reconstructed images and quantitatively analyzed cerebral blood flow (CBF). Results The 3D-ASL of TIA patients showed
that the patients with hypoperfusion on the affected side were significantly more than those on the healthy side, and the difference was
statistically significant (P<0.05). The mean CBF of the affected side of TIA patients [(25.0±9.6) mL/(100g·min)] was statistically
lower (P<0.05) than that of the healthy side [(44.0±13.5) mL/(100g·min)]. 3D-ASL showed that 27 patients (75.0%) with reduced
perfusion of the affected side. MRA showed that there were 16 patients (44.0%) with vascular stenosis. The combined application of
3D-ASL and MRA showed that there were 29 cases (80.0%) with abnormality. The diagnostic accuracy of the joint examination was
higher than the 3D-ASL examination or the MRA examination. Conclusion 3D-ASL technology can detect early blood perfusion
abnormalities that cannot be found in routine MR examination in TIA patients. Combined with MRA, it can improve the diagnostic
accuracy of TIA.
