Research progress in imaging technology of the vascular stenosis evaluation

Vascular stenosis can mainly be divided into two types: the congenital vascular stenosis and acquired vascular stenosis.The etiology of congenital vascular stenosis is unclear yet, it usually occurred in different types of congenital cardiovascular and cerebrovascular stenosis.Acquired vascular stenosis is often caused by atherosclerotic plaque, resulting in the percutaneous brace implantation, or balloon angioplasty.Imaging methods can be helpful in the clinical diagnosis and evaluation of various congenital or acquired vascular stenosis accurately and timely.Currently, imaging technology has developed rapidly and the new imaging technology emerges.This paper briefly reviews the imaging technology progress in evaluating the vascular stenosis.
