Validation of transcranial Doppler ultrasound with an in vivo stereotactic technique.
نویسندگان
چکیده
Magnetic resonance (MR)-guided stereotactic techniques that allow precise in vivo anatomic location have recently been developed (1). Using such a system, we tested the hypothesis that we are insonating from the midpoints of the M 1 segment of the middle cerebral artery and A 1 segment of the anterior cerebral artery during clinical hand-held transcranial Doppler examinations. We also compared our routine maximum mean linear blood flow velocity (peak velocity) measurements with those obtained using the MR-guided stereotactic technique.

Frequency of Opium Addiction with Ischemic Stroke Patients and Comparing Their Cerebrovascular Doppler Ultrasound Alternations to Non-Addicts
Background: Ischemic stroke is a major cause of mortality and morbidity worldwide. Various studies on the etiology of this disease are in progress. Some studies have suggested that opium abuse may is associated with increased risk of ischemic stroke. The present study aimed to analyze the frequency of opium addiction and to compare cerebrovascular ultrasound patients’ changes to non-addicts. Me...

Abstract Background: Transcranial Doppler ultrasonography results have not been previously studied in among Iranian sickle cell anemia patients. The present study was performed to evaluate the pattern of intracranial flow velocities among Iranian children with sickle cell anemia and the hematological parameters that can affect the time-averaged mean of maximum velocity in major intracranial...
متن کاملCerebral 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...
متن کاملIn-vivo Imaging of Magnetic Fields Induced by Transcranial Direct Current Stimulation (tDCS) in Human Brain using MRI
Transcranial direct current stimulation (tDCS) is an emerging non-invasive neuromodulation technique that applies mA currents at the scalp to modulate cortical excitability. Here, we present a novel magnetic resonance imaging (MRI) technique, which detects magnetic fields induced by tDCS currents. This technique is based on Ampere's law and exploits the linear relationship between direct curren...
