To establish the reliability and clinical significance of transcranial ultrasonic harmonic
perfusion imaging (HPI), we evaluated HPI's relationships with transcranial Doppler (TCD) …

Pulse-inversion contrast harmonic imaging is a new ultrasonographic technique that can
assess brain perfusion. In an adult with moyamoya disease and multiple recurrent strokes …

Doppler ultrasound has been used in medicine for many years. The primary long-standing
applications include monitoring of the fetal heart rate during labor and delivery and …

Ultrasound harmonic imaging of perfusion after ultrasound contrast agent (UCA) bolus
injection (BHI) can detect cerebral perfusion deficits. In a pilot study, we evaluated the ability …

The purpose of this study was to evaluate the potential of contrast-enhanced three-
dimensional (3-D) power Doppler (CE3DPD) in the assessment of intracranial vascular …

1. Rationale and Objectives Application of ultrasound contrast agents (UCA) in transcranial
color coded sonography (TCCS) has been evaluated throughout the last years for vascular …

Phase inversion harmonic imaging (PIHI) with newer contrast agents can display
parameters of cerebral perfusion either using the established ipsilateral approach, or the …

Assessment of the cerebral blood-flow-reserve in patients with cerebrovascular diseases is
extremely important in terms of making prognosis, determining treatment tactics, and …

The aim of this study is to compare the ability of mean frequency-based colour Doppler (CD)
and power Doppler (PD) to identify the basal cerebral arteries in normal subjects. Fifty …
