Intracranial atherosclerotic diseas

Intracranial atherosclerotic disease is a major cause of isch-
emic stroke worldwide and the most common cause in the Asian population.

high.2 For many years, lumenography-based methods were
used to assess intracranial atherosclerotic disease by means
of luminal narrowing, and it was thought that stenosis grade
was an accurate reflection of disease burden.3In recent years,
