Transcranial doppler sonography diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine

Background: An imbalance of the cerebrovascular response during functional activation of the brain has been postulated as a factor in the pathophysiology of migraine. The purpose of this study was to determine the transcranial doppler sonography (TDS) diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine. Methods: This study was carried out on 46 pa...

Interhemispheric comparisons of cerebral blood flow velocity changes during mental tasks with transcranial Doppler sonography.

OBJECTIVE The purpose of this study was to evaluate hemispheric asymmetry of cerebral blood flow changes during various mental tests by applying transcranial Doppler sonography (TCD) to simultaneously monitor bilateral cerebral blood flow velocity changes. METHODS Twenty-one participants without cerebrovascular disease performed 3 left hemispheric tasks (reading, calculation, and color scalin...

Changes in blood flow velocity and diameter of the middle cerebral artery during hyperventilation: assessment with MR and transcranial Doppler sonography.

PURPOSE To compare blood flow velocity changes within the middle cerebral artery (MCA) during hyperventilation, as measured with by both transcranial Doppler sonography and MR imaging, with the diameter of the MCA as measured with MR imaging alone. METHODS The studies were performed in six healthy volunteers ranging in age from 22 to 31 years (mean, 27 years). Transcranial Doppler sonography ...

Importance of angle correction in the measurement of blood flow velocity with transcranial Doppler sonography.

BACKGROUND AND PURPOSE The angle of insonation cannot be assessed with conventional transcranial Doppler sonography. Findings in healthy control subjects suggest that the angle is relatively small in routine clinical practice. Data regarding the angle in middle cerebral artery (MCA) stenosis are scarce. In this study, the angle and its effect on flow velocity measurements were assessed with tra...

Cerebral hemodynamic in patients with major β-Thalassemia using transcranial Doppler sonography

Background: β-thalassemia, a severe form of anemia, is an inherited blood disorder characterized by growth retardation, splenomegaly, and bone abnormalities. Complications related to treatment-induced iron overload also affect the quality of life of patients with major β-thalassemia. Some recent studies indicated cerebral hemodynamic disorders and increased risk of stroke in these patients. The...
