====== Tortuosity ======
 
Tortuosity is a property of curve being tortuous (twisted; having many turns). There have been several attempts to quantify this property. 

see [[Middle cerebral artery tortuosity]].

see [[Tortuous vertebral artery]].

[[Blood vessel]] [[tortuosity]] may play an important role in the development of vessel abnormalities such as [[aneurysm]]s.

The greater intracranial arterial tortuosity in [[Korea]]ns with vascular risk factors may in part explain the higher prevalence of  intracranial artery atherosclerosis (ICAS) in [[Asia]]ns than in whites. Further studies are required to prove these preliminary findings
