Carotid ultrasonography has become the preferred imaging technique for screening patients
with suspected atherosclerotic cerebrovascular disease. The principles underlying duplex …

Advancements in technology have brought noninvasive diagnosis of cerebrovascular
disease to a high level of accuracy in a relatively short period of time. Conventional duplex …

Initial experience with a pulsed Doppler device coupled to a high resolution real-time
sonographic scanner for noninvasive evaluation of extracranial carotid disease is reported …

Directional continuous wave Doppler ultrasonography has been used to assess the
extracranial carotid arteries of over 500 patients, 90 of whom have had angiography …

The results of two methods for noninvasively diagnosing carotid disease are described. In
the first study, a color‐coded continuous‐wave Doppler scanner was used. As evaluated by …

Technical advances in the field of ultrasound have resulted in the development of a high
resolution real-time B-mode imaging system that permits direct Doppler analysis of …

Recent advances in ultrasound technology have made possible the development of
diagnostic instruments that combine cross-sectional imaging and Doppler analysis. These …

Carotid duplex ultrasonography is a noninvasive technique for hemodynamically significant
stenosis detection and cardiovascular risk estimation. Anatomic information of carotid …

The duplex ultrasonic scanner combines real-time B-mode imaging with a single-gate,
variable-range pulsed Doppler. The detection and categorization of the severity of carotid …

Duplex scanning of the carotid arteries combines B‐mode ultrasound and Doppler
ultrasound within a single instrument, thus providing both anatomical imaging of the vessel …
