Purpose
Among various modern radiologic methods,
the magnetic resonance imaging (MRI) is the most perspective for surveying of morphological and functional conditions of the cerebral vascular system.
It provides the widest range of approaches to visualization of the CNS and cerebral hemodynamics comparing to all other existing radiologic methods.
MR angiography also allows measuring quantitative characteristics of liquid flows applying the Quantitative Flow (Q-Flow) technique [1].
Being used together with other impulse sequences,
Q-Flow provides extended results of morphological and functional survey of the vascular structures of head and neck,
as well as collects reliable quantitative characteristics of arterial blood flow.
Kinking and coiling of the internal carotid artery (ICA) sometimes may result in symptomatic cerebrovascular disease,
but indisputable evidence linking the two conditions is lacking [2].
By definition,
in the carotid artery syndrome the offending carotid artery is held responsible only for the following features: (1) contralateral hemiparesis,
which may be transient,
or hemiplegia,
with or without sensory deficit; (2) ipsilateral monocular visual dysfunction; (3) ipsilateral frontal headache; (4) homonymous field defects; and (5) language defect (partial or complete) only when the dominant hemisphere is involved.
Symptoms such as syncope,
confusion,
roaring in the ears,
and memory loss when cited as being due to ipsilateral carotid artery disease are considered only when the total angiographical report permits a clinicopathological correlation [3].
Thus,
the purpose of our research was to study and quantify hemodynamic parameters of arterial blood flow by internal carotid arteries (ICA) in volunteers and patients with bilateral ICA coiling using phase contrast MRI.
