APTw
imaging may be used as one effective method in diagnosing symptomatic
intracranial artery stenosis, and provide additional clinical value on the
basis of 3D-ASL imaging.
Figure 1 A.
48-year-old male with an occlusion in the right MCA. B. 49-year-old male
with severe stenosis of the left ICA C7 and L-MCA M1. (a) High
APTw value area was visible (black arrow). (b) Perfusion was lower in the
ipsilateral side than the contralateral side (white arrow).
Figure 2
The ROC curve showed the sensitivity and specificity values of APT and 3D-ASL
in the diagnosis of symptomatic intracranial artery stenosis. The diagnosis of combined
ASL and APT(AUC=0.997, P＜0.001)
shows the most robust diagnostic performance in SIAS.
