The role of the acoustic radiation force in color Doppler twinkling artifacts
PURPOSE The aim of this experimental study was to evaluate whether the acoustic radiation force (ARF) is a potential source of twinkling artifacts in color Doppler images. METHODS Color Doppler images were obtained using a clinical ultrasonic scanner (Voluson e, GE Healthcare) for a high contrast (+15 dB) circular scattering phantom at pulse repetition frequencies (PRFs) ranging from 0.1 to 1...
متن کاملColor Doppler twinkling artifacts in various conditions during abdominal and pelvic sonography.
OBJECTIVE The aims of this study were to describe the mechanisms likely to be responsible for color Doppler twinkling artifacts and their associated machine factors and to illustrate the various conditions that cause twinkling artifacts and those pitfalls. METHODS We evaluated various sonographic machine-associated factors that influence artifact appearance and identified various conditions t...
متن کاملTwinkling artifact on intracerebral color Doppler sonography.
Transcranial Doppler sonography shows potential as a noninvasive technique for long-term follow-up of treated intracranial saccular aneurysms. This technical note describes a color Doppler artifact related to microcoil architecture that might represent a potential pitfall in transcranial Doppler sonographic evaluation of aneurysmal cavity thrombosis, since it may be wrongly interpreted as resid...
متن کاملTwinkling artifact in color Doppler imaging of the orbit.
OBJECTIVE To show an artifact related to color Doppler flow imaging of the orbit. METHODS Three patients with strongly reflective structures in the orbit were selected from those routinely referred by clinicians for color Doppler ultrasonography of the orbit. Gray scale and color flow images were obtained with a 7.5-MHz linear array probe for a region with strongly reflective structures. A sp...
