As an emerging intravascular imaging technology, intravascular optical coherence tomography (OCT) has been recognized for its clinical application value in the continuous exploration of the past decade. With its high resolution, OCT can clearly display the subtle morphological features of arterial stenosis lesions, help select treatment options, guide stent placement, and evaluate stent-vessel relationship and neo-intimal coverage after stent implantation for timely detecting early and late complications after stent placement. In recent years, a series of studies have also explored the value of OCT in the evaluation of cerebral angiography and intracranial and extracranial artery stent placement. We made a review of this topic.
