This is the maximum averaging value that our scope provides. Objective: Transcranial Doppler is a technique which is being used ever more frequently in the study of intracranial arteries and is very useful in the study of cerebrovascular disease. The typical values of a healthy population in our country are unknown.

Calculations and statistical methods Transcranial Doppler (TCD) is a noninvasive ultrasound (US) study used to measure cerebral blood flow velocity (CBF-V) in the major intracranial arteries. It involves use of low-frequency (≤2 MHz) US waves to insonate the basal cerebral arteries through relatively thin bone windows. TCD allows dynamic monitoring of CBF-V and vessel pulsatility, with a high temporal resolution. It Normal mean flow velocities within the Ml-segment, the posterior cerebral artery, the carotid siphon and the basilar trunk were 58±15.6, 39±9.9, 47±13.8 and 41±10 cm/s, respectively, and revealed a marked decrease with age. Intraindividual side-to-side differences were low.

Systolic diastolic ratio (S/D) Represents the ratio between PSV and EDV. This is not used for clinical purposes. We present the examination technique and normal values of flow velocity from intracranial basal cerebral arteries for a recently developed pulsed Doppler system operating at 2 MHz emitting frequency.

Transcranial Doppler (TCD) sonography is being used as a primary tool for the non-invasive diagnosis of cerebral vasospasm. The AHA/ASA guidelines on the management of aneurysmal subarachnoid hemorrhage (2012) recommends the use of transcranial Doppler (TCD) as a reasonable technique for monitoring the development of cerebral vasospasm (Class II a, Level).

Types of Doppler •Continuous-wave –display information representative of all moving targets in the ultrasound beam. •Pulsed-wave –uses short bursts of ultrasound with “range gating” to facilitate signal analysis from a small area at a specified depth from the transducer. –TCD uses Pulsed-Wave Doppler What type of Doppler is TCD?
