Transcranial Doppler Ultrasonography

Neurosurgery Clinics of North America, 1994
Transcranial Doppler ultrasonography is an extremely useful adjunct in neurosurgical intensive care. Continuous improvements in TCD equipment as well as computer software have improved examination success and also vessel identification. Recent expanding applications of TCD have also allowed the study of disorders of control of the cerebral circulation.

[Gynecologic Doppler ultrasonography].

Ultraschall in der Medizin (Stuttgart, Germany : 1980), 1991
The resistance of the vessel of the ovarian artery changes during the cycle. At the time of ovulation the resistance of the vessel of the ovarian artery decreases under the influence of steroid production in the ovary. The resistance decreases and the blood flow increases.

Transcranial doppler ultrasonography

Journal of neurology, neurosurgery, and psychiatry
Abstract Transcranial Doppler ultrasonography (TCD) is a noninvasive, bedside procedure that can detect blood flow in the proximal cerebral intracranial arteries. TCD has multiple applications, including rapid assessment of anterior circulation blood flow in acute, large-vessel occlusion. For patients with subarachnoid hemorrhage, trends

Advances in transcranial doppler ultrasonography

Current Neurology and Neuroscience Reports, 2008
Transcranial Doppler ultrasonography (TCD) is the only noninvasive real-time neuroimaging modality for the evaluation of characteristics of blood flow in basal intracerebral vessels that adds physiologic information to structural imaging. TCD has been rapidly evolving from a simple noninvasive diagnostic tool to an imaging modality with a broad ...

Hysterosalpingography with color Doppler ultrasonography

American Journal of Obstetrics and Gynecology, 1991
To assess the accuracy of the diagnosis of tubal occlusion with the use of color Doppler flow ultrasonography and hysterosalpingography, 129 infertile women were studied. All 129 women had the procedure performed with an ATL Ultramark 9 (Advanced Technology Laboratories, Bothel, Wash.) color Doppler ultrasonography machine. Eighty-five of the 129 women

Transcranial Doppler Ultrasonography

2019
Abstract Transcranial Doppler (TCD) ultrasonography is a diagnostic technology for ascertaining numerous physiologic and pathologic phenomena by monitoring the direction and velocity of blood flow in intracranial vasculature. It is a noninvasive, point-of-care diagnostic tool that provides continuous and reproducible bedside data without

Transcranial colour Doppler ultrasonography

Rivista di Neuroradiologia, 2001
Transcranial colour Doppler ultrasonography (TCCD), being a non-invasive method is an invaluable source of information on cerebral haemodynamics. It is the blood flow disturbances that often lead to irreversible ischemic lesions, which can then be detected a posteriori with various imaging techniques.

Doppler Ultrasonography and Contrast-Enhanced Ultrasonography

Choonpa Igaku, 2006
胆道疾患に対する超音波カラー・パワードプラ法と造影超音波に関する最近の知験をレビューした. 超音波カラー・パワードプラ法は脈管と胆管の鑑別に有用であり, これは閉塞性黄疸時における経皮経肝的胆道ドレナージを安全に施行するために有用である. 一方, 胆嚢内腫瘤の鑑別にも超音波カラー・パワードプラ法は有用であり, 胆嚢癌では腫瘍血管および胆嚢動脈の最高流速が上昇する. 胆嚢癌のhigh risk groupである膵胆管合流異常は, 胆嚢壁の動脈流速が上昇するといわれ, カラードプラ法が診断の契機となる. 胆嚢ポリープの鑑別においては, 胆嚢癌は造影超音波で樹枝状の血管構築を呈することが多い点が他のポリープとの鑑別点になる.
